Study On The Durability Of Non-toxic Multicolor Acrylic Paint Marker Pens

INTRODUCTION
In today's vibrant stationery market, non-toxic multicolor acrylic paint marker pens are popular with consumers, especially children and creative professionals. It has colourful, easy to use, non-toxic and other features, in painting creation, handicraft making, household goods and other aspects of popular. However, in addition to focusing on color richness and security, color durability is also a key factor affecting users. After all, no one wants their painstaking creations to fade anytime soon. So, how durable is the non-toxic multicolor acrylic paint marker pens and how easy is it to fade? This paper will explore from different scenes and material perspectives.
Fading Daily Usage Scenarios
Normal indoor environment
Normal indoor environments with dry, light and temperature are the most common conditions in our daily lives. In this environment, we observed patterns drawn by nontoxic polychromatic acrylic paint marker pens for a long period of period (months or even years). Over time, it was found that under normal conditions, there was no noticeable change in colour brightness or saturation. This is because acrylic coatings themselves have a certain stability and weather resistance. In a dry, light-resistant environment, its molecular structure remains relatively stable and is not susceptible to chemical reactions leading to discoloration. After a few years of long storage, some colors appear slightly dull, but overall there was no noticeable fade, the pattern could still maintain a relatively clear outline and vivid colors.
Frequent Touch and Friction Scenarios
There is a lot of contact and friction in everyday life. For example, children may often touch their paintings with their hands, or handicrafts dyed with these marker pens may be touched frequently. Frequent contact and friction can have an impact on paint. In terms of impact mechanism, friction can damage the molecular structure of coating surface, causing some coatings to fall off or disperse. Through actual observation, it was found that the durability of color is affected in this case. However, the effect is not immediate and will be felt gradually after a certain amount of friction. In addition, different quality marker pens have different friction resistance. A high quality marker pen will bind paint and paper more tightly together, so it has more friction resistance and is less prone to fading quickly.
Color Performance in Special Environments
Humid Environment
Humid environments have a big effect on paint. Bathrooms, basements, etc., have high air humidity and paint absorbs moisture easily. When the coating absorbs moisture, its molecular structure changes, leading to color changes and discoloration. After being placed in the wet for some time, we found signs of flaking and flaking in patterns painted with non-toxic polychrome acrylic paint marker pens. This is because moisture can seep between paint and paper, breaking the bond between paint and paper and preventing the coating from adhering firmly to the paper. As a result, the color durability of these marker pens is greatly reduced in humid conditions.
Sunny Environments
Sunlight exposure is also an important factor affecting color durability. Placing a created work by a window and exposing it to the sun for long periods of time each day causes the pigment molecules in the pigment to undergo photochemical reactions due to prolonged exposure to the sun, causing the color to fade. In addition, different colors fade at different speeds. In general, bright colors such as red and yellow fade faster, while dark colors such as black and dark blue fade more slowly. This is because brightly colored pigment molecules are relatively unstable and more susceptible to light and breakdown.
Color Durability on Different Materials
We have selected common printing paper, cardboard box, sketch paper, watercolor paper and other commonly used paper materials to carry out experiments. We used non-toxic multicolor acrylic paint marker pens to draw the papers and set the same time and storage conditions. Through observation and analysis, it was found that different kinds of paper have a great influence on color durability. Cardstock and watercolor paper have rougher surfaces that allow paint to penetrate and stick, so they have better color durability. On the other hand, plain printing paper has a smooth surface, weak paint and fades easily. Sketch paper is somewhere in between.
Conclusion:
Based on these exploration results, the color durability of non-toxic multicolor acrylic paint marker pens varies in different situations and materials. color durability is better in normal indoor environments, with frequent exposure and friction scenarios having an impact on color durability. Humidity and sunlight exposure greatly reduce color durability, and cardboard boxes and watercolor paper are more conducive to color durability in different paper materials. Therefore, when using these stationery items, consumers should avoid placing them in humid and sun-exposed environments and choose suitable paper materials for their creations in order to prolong the color life of their works.
