FLAME RETARDANT PHOTOPOLYMERIZABLE COMPOSITION AND FLAME RETARDANT ADHESIVE SHEET AND FLAME RETARDANT TACKY TAPE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a photopolymerizable composition having excellent shear strength, release strength and flame retardancy and obtain an adhesive tape and a tacky tape by using the composition. ;SOLUTION: This photopolymerizable composition is obtained by blending 100 pts.wt. monomer mixture containing 50-98wt.% 1-12C (meth)acrylic acid ester monomer (a), 50-2wt.% monomer having a polar group and copolymerizable with the monomer (a) and 0.01-1wt.% monomer copolymerizable with these monomers (a) and (b) and having ≥2 unsaturated double bonds in the molecule with 0.01-5 pts.wt. photopolymerization initiator and 5-70 pts.wt. flame retardant such as ammonium polyphosphate.;COPYRIGHT: (C)1997,JPO
