LIGHT SHIELDABLE SELF-ADHESIVE LAMINATE

PURPOSE:To prevent transfer of a light shieldable dye to an adherend by adding polyvalent isocyanate as a crosslinking agent and a urea resin or melamine resin as a hardener in conjunction to a light shieldable self-adhesive agent compsn. prepd. by using an acrylic self-adhesive agent as a base and adding the light shieldable dye thereto. CONSTITUTION:This laminate is formed by laminating the light shieldable self-adhesive agent layer 2 on one face of a transparent plastic base 1. The light shieldable self-adhesive agent layer 2 is formed of the self-adhesive agent which consists of the acrylic self-adhesive agent and the light shieldable dye and further, the polyvalent isocyanate and the urea resin or melamine resin. The mobility of the light shieldable dye is suppressed by crosslinking the light shieldable self-adhesive agent layer of the acrylic system or the functional group of the light shieldable dye is fixed to the resin by reaction with a free amine group or isocyanate group. The transfer of the dye in the light shieldable self-adhesive agent to the adherend and the remaining of the adhesive agent of the light shieldable self-adhesive laminate are thereby prevented even if the laminate is stuck to the adherend. As a result, a precision photomechanical process is enabled.
