Abstract

Organic pigments have insufficient barrier properties, they perform a decorative function, unlike inorganic pigments. Organic pigments are often used in admixture with inorganic pigments, fillers, resulting in decreased light fastness. To increase the lightfastness can be structural coloration of polymeric materials. Practical interest is the study of the impact of structurally-colored alkyd resin coatings for lightfastness.

The lightfastness of the structurally-colored alkyd resins evaluated in the following manner. The paint obtaining from structurally- colored alkyd resins was applied on a glass plate, which after drying is placed under the radiation of the xenon lamp. Plates covered 1/3 opaque paper to ultraviolet rays. After the required time, opaque paper pushed away by another 1/2 of the total length of the plate. After it was determined color change, loss of gloss, cracking, nets and so on.

Films produced with the starting dyes in the same conditions were used as a control samples.

Experimental data have shown that lightfastness of the structurally-colored alkyd resins above the control samples, indicating the slow process of photodegradation of structurally-colored alkyd resins.

The lightfastess research data of paints confirm that colored alkyd resins have several advantages over dyes (pigments) and may be used in the preparation of paints.
