- the present invention relates to a release film for transfer foil precursor and a transfer foil precursor that does not spill out when slitting so as to have a width appropriate for transfer.
- the transfer layer is formed into a plastic molded article, a glass molded article, a metal mold
- a thermal transfer method in which after decorating the transfer film such as a product etc., the above-mentioned release film is peeled off and only the transfer layer is transferred to the surface of the transfer object for decoration.
- the transfer foil is sandwiched in a molding die, resin is injected and filled in the cavity, and at the same time the plastic molded product is obtained, the transfer layer is adhered to the surface.

- the transfer foils used in the above-described thermal transfer method and simultaneous molding transfer method are uneconomical if they are individually manufactured with a width matched to the size of the transferred object at the time of transfer, as shown in FIG.
- the foil 109 is produced in a wide width, and is transferred after being slit to an appropriate width according to the size of the transferred object 108.
- the drawback is that there are many handle layers as the transfer layer, or if it is necessary to provide a vapor deposition layer as the handle layer, if the release layer must be thick like hard coat foil, if there are many functional layers, etc. As the transfer layer becomes thicker as a whole, it was more remarkable.
- the foil spillage adheres to the transfer foil 109 of a predetermined width obtained by slitting the raw fabric, and enters as a dust between the material to be transferred 108 and the transfer layer at the time of transfer.
- the transfer foil 109 of a predetermined width obtained by slitting the raw fabric, and enters as a dust between the material to be transferred 108 and the transfer layer at the time of transfer.

- the peelable film has an appearance difference distinguishable between the treated area and the non-treated area subjected to the easy adhesion process
- the pattern layer is not subjected to the easy adhesion process in the printing step. Even when an overlapping defect section occurs, only the defect section can be easily removed based on the appearance difference, and when transfer is performed using a transfer foil after slitting, a peeling defect of the pattern layer occurs. It never happened.
- the present invention can be used as a release film for a transfer foil material and a transfer foil material used for a thermal transfer method, a molding simultaneous transfer method and the like.

Abstract
Description
前記転写箔原反のスリット位置に対応する前記剥離フィルムの剥離面に、表面改質による易接着処理が帯状に施されていることを要旨とする。
前記転写箔原反のスリット位置に対応する前記剥離フィルムの剥離面に、表面改質による易接着処理が帯状に施されていることを要旨とする。
650mm幅、厚み38μmの2軸延伸ポリエチレンテレフタレートフィルムを、転写箔原反10のスリット部分を除いてマスクし、プロパンガスの炎の下を50m/minで通過させることによって、当該フィルムの片面にフレーム処理(易接着処理)を150mmピッチで10mm幅の帯状に施し、転写箔原反用剥離フィルムとした。
650mm幅、厚み38μmの2軸延伸ポリエチレンテレフタレートフィルムをベースフィルムとし、その片面に、エポキシメラミン樹脂を主成分とするインキをグラビア印刷した後、170℃で20秒間加熱することにより厚み約1μmの離型層を全面的に形成した。

650mm幅、厚み38μmの2軸延伸ポリエチレンテレフタレートフィルムの製膜時に、フィルムの片面にかつ全面的にインラインコーティング法で、インディゴ染料で薄い濃度の色をつけた0.02μmのシリコーン層を離型層として設けた。
