Abstract
A base sheet and a heat transfer sheet are herein provided and make it possible to cut out any arbitrary figure or design from the heat transfer sheet having a thin heat transferable layer with an automatic cutting machine. The base sheet has a first support member and a second support member peelably integrated with the first support member, while the heat transfer sheet has the foregoing base sheet and the transferable layer formed on the second support member of the base sheet optionally through a releasing layer.
Claims4
A method for thermally transferring a design to an article, comprising the steps of:
- preparing a heat transfer sheet, wherein said heat transfer sheet comprises a base sheet having a first support member and a second support member peelably integrated with said first support member on a first surface of said second support member, a first releasing layer being formed on a second surface of said second support member, and a thermally transferable layer, having a thermally adhereable resin, formed on said first releasing layer;
- cutting out along a periphery of a design by a depth which reaches from said thermally transferable layer through said second support member toward a surface of said first support member;
- removing unnecessary portions of said thermally transferable layer and said second support member, corresponding to the unnecessary portions of said thermally transferable layer, to obtain said thermally transferable layer having shapes of the design which is supported by said second support member, having a same shape as remaining portions of thermally transferable layer, and said original first support member;
- contacting a surface of said remaining portions of thermally transferable layer with a surface of the article to form a composite body;
- subjecting said composite body to heating and pressure to thermally transfer the thermally transferable layer from the releasing layer to the surface of the article;
- and
- peeling of said second support member from the thermally transferred thermally transferable layer on the article.
