DECORATION SHEET, POLYCARBONATE-BASED POLYURETHANE RESIN FOR FORMING THE SAME AND WATER-BASED INK CONTAINING THE RESIN

摘要

PROBLEM TO BE SOLVED: To provide a decoration sheet suppressing blocking when winding is once carried out at the step of forming a picture pattern layer, and also excellent in color property and weathering stability of the picture pattern layer.

SOLUTION: In the decoration sheet formed with at least a picture pattern layer on a substrate sheet, the picture pattern layer is formed of water-based ink including a polycarbonate-based polyurethane resin obtained by reaction of a polyfunctional compound containing liqid polycarbonate polyol at 20°C and a raw material mixture containing polyisocyanate.
