ABSTRACT:
A transfer sheet is here disclosed which is prepared by forming a highly glossy pattern layer of an ink containing a curable resin and silicon resin on the matte surface of a base sheet which is excellent in release characteristics to the thermosetting resin. In addition, a method for the preparation of a thermosetting resin decorative material is also disclosed which comprises the steps of superposing the above-mentioned transfer sheet on a resin-impregnated paper so that the pattern layer on the transfer sheet may be brought into contact with the resin-impregnated paper; then heating and pressing the resulting laminate; and after the curing of the resin in the resin-impregnated paper, releasing the transfer sheet therefrom.
