A photoactive mixt. comprises by wt. (A) 100 pts. of a compsn./ polymer of 50-100 pts. acrylic monomer and 0-50 pts. copolymerizable, monoethylenically, unsatd. monomer; and (B) 0.01-2 pts. of a chromophore-substd. halomethyl-s-triazine of formula (I), where R1-4 are each H or an alkoxy gp. with 1-3 of the RS being H. The mixt. is specifically concerned with pressuresensitive adhesive tapes, but tack-free prods. can also be used as photo-resists or as viscoelectric damping material lackifiers, reinforcing agents and other modifiers. Some of these may copolymerize with the acrylic monomer or photopolymerize independently and can be blended with the photoactive mixt. |
