Summary:PURPOSE:To obtain a self-adhesive compsn. which has such an excellent ultraviolet resistance that the self-adhesive properties are maintained and neither remaining nor discoloration of the adhesive occurs even when exposed to direct ultraviolet rays, e.g. in the outdoor use by using a copolymer obtd. from a monomer mixture contg. a 1-aryl-6-heptene-1,3-dione. CONSTITUTION:A monomer mixture comprising 1-10 pts.wt. 1-aryl-6-heptene-1,3- dione, 35-80 pts.wt. acrylic and/or methacrylic ester, and 3-15 pts.wt. alpha- monoolefincarboxylic acid is subjected to free-radical polymn. in an org. solvent (e.g. toluene or ethyl acetate) or in an aq. medium to give a copolymer which has the function to effectively absorb ultraviolet rays with wavelengths of 400nm or lower.
