METHOD OF MANUFACTURING MATERIAL WITH DECORATIVE COATING Russian patent published in 1998 - IPC

FIELD: materials for furniture and interior finishing. SUBSTANCE: material consists of internal board and outside polymer coating manufactured by applying polymerizable composition including (in wt %): oligoesteracrylate, 30-40; mineral filler, 48-61; plasticizing additive, 3-10; photoinitiator, 1-10; and pigment, 0.01-1. The latter may be iron oxide, carbon black, phthalocyanine dyes or their mixture. Hardening of composition is initiated by UV radiation of mercury lamp with power at least 1 kW. Thickness of hardened coating is 1-2 mm. To extend color spectrum of dyed decorative material, polymerizable composition is supplemented by 0.01-5 wt % of a fat-soluble dye. Surface relief may be reduced by placing silicate glass sheet onto polymerizable composition prior to be UV irradiated. EFFECT: improved decorative quality of coating. 3 cl, 2 tbl
