Özet
Enhancing fastness properties of thermochromic dyes and pigments provide unique and assertive design opportunities and an innovative approach for leather industry.For this purpose, the ageing behavior of thermochromic pigments (cold and touch activated) used in leather finishing process by the addition of UV absorbent and cross-linker was investigated.The color changing effect of thermochromic leathers was determined spectrophotometrically prior and subsequent to accelerated ageing tests performed under two different conditions (only heat and heat associated with relative humidity).No significant effect of ageing was found on thermochromic leathers.However, a partial decrease was determined for the cold activated leathers and it was prevented by the use of UV absorbent and cross-linker.
