Abstract
An adhesive prepared by blending a hardening resin serving as the main component with an urethane resin having a polycarbonate structure. The addition of the urethane resin with the polycarbonate structure makes it possible to give an adhesive which has a high solvent resistance and a good low temperature impact resistance and achieves good adhesion between vinyl chloride and a steel plate. This urethane resin can be obtained by reacting a polyol with an isocyanate compound. It is advantageous to use the urethane resin in an amount of 5 to 35% by weight.
