发明名称 THERMALLY BONDABLE FLAME-RETARDANT POLYESTER FILM
摘要 PURPOSE:The titled film useful for flat cable, etc., having improved blocking resistance, adhesiveness and flame retardance, obtained by forming a primer layer and a flame-retardant adhesive layer consisting of a flame-retardant and an adhesive containing silicic acid on a polyester film. CONSTITUTION:(A) One side of a polyester film 1 is provided with (B) a primer layer 2 comprising (i) a saturated copolymerized polyester resin as a main component and (ii) a thermally curing agent (e.g., 2,4-tolylene diisocyanate, etc.,) and (C) a flame-retardant adhesive layer 3 to give the aimed film. The layer 3 consists of (iii) 25-45pts.wt. first component [-20-5 deg.C glass transition temperature (Tg) and 100-150 deg.C softening point] of the saturated copolymerized polyester, (iv) 5-25pts.wt. second component (45-70 deg.C Tg and 155-180 deg.C softening point) of the saturated copolymerized polyester, (v) 30-60pts.wt. flame- retardant and (vi) 1-10pts.wt. silicic acid.
