Nustatyta, kad ri‰ikliai organiniuose tirpikliuose, mai‰ant juos su pigmentais,sudaro matines daϘ dangas, o vandeniniai ri‰ikliai – blizgias, kurios blizgiomisi‰lieka net ir po fotocheminio sendinimo.5. I‰tirta, kad daϘ su ri‰ikliu Paraloid B-72 etilo alkoholyje blizgumas didesnisnegu daϘ su ri‰ikliu Paraloid B-72 toluene, bet daϘ blizgumo pokytissenòjimo procese maÏesnis ri‰iklio Paraloid B-72 toluene.6.

In this experiment, the tested binders for theretouch paint were prepared from acryl copolymers and the solvents appropriatefor them. The binders were mixed with 21-colour pigments for making paintsamples. The properties of the made paint were evaluated visually and by optictest tools after measuring changes in glittering, the color tone, richness, lightnessand a general shade before and after artificial (photochemical) ageing. The mostproper binder for the majority of the pigments exploited in the experiment wasacrylic copolymer Paraloid B-72 dissolved in toluene. It has been proved by theevaluation of the results of the changes in lightness, richness of colour, glitteringand a general shade.T YRINñ JIMAI / 23
