Embodiment

[0176] The following examples are given to illustrate the present invention more specifically, but the present invention is not limited to the following examples unless the gist is exceeded.

[0177] However, "part" and "%" in an example refer to a basis of weight.

[0178] [Evaluation of samples for evaluation]

[0179] (1) Releasability

[0180] The releasability when the base film [I] was peeled from the sample for evaluation by hand was evaluated by the following reference|standard.

[0181] ◯: The base film can be easily peeled off.

[0182] Δ: Peeling from the base film was possible, but was accompanied by peeling noise.

[0183] ×: There was difficulty in peeling off the base film, and peeling marks remained on the surface of the protective layer.

[0184] (2) Surface gloss of the protective layer

[0185] After the base film [I] was peeled off for the evaluation sample, the fluorescent lamp was reflected on the surface of the protective layer (cured curable resin ...

Abstract

The invention provides a polyving akohol thin film having excellent release property suitable for a basic film for a heat transfer printing stack and a manufacturing method thereof, the heat transfer printing stack using the thin film and a heat transfer printing method using the stack. The polyving akohol thin film is characterized in that 1-15 weight parts of poly alkylene glycol (B) with the weight-average molecular weight below 1000 is included with respect to 100 weight parts of polyving akohol resin (A).

Description

technical field [0001] The present invention relates to a polyvinyl alcohol-based film that can be suitably used as a base film of a laminate for thermal transfer, and more specifically, to a laminate for thermal transfer that is excellent in mold release properties and can provide an excellent surface of the resulting decorative molded article A polyvinyl alcohol-based film, a method for producing the polyvinyl alcohol-based film, a thermal transfer laminate using the polyvinyl alcohol-based film, and a thermal transfer method using the thermal transfer laminate. Background technique [0002] As a method of decorating a molded article, there is a method of transferring a transfer layer of a transfer film using a transfer film. The transfer film is laminated with a transfer layer on the base film, and the transfer layer may include a resin layer as a protective layer for protecting the surface of the material to be transferred after transfer, and a pattern layer on the resin...
