Problems solved by technology

Although the machining suitability has been improved, there is still a problem that the fine unevenness of the embossing process and the matting process will affect the surface of the printed layer and reduce the accuracy of the printed image.
[0006] Moreover, since the non-printing side of these films for hydraulic transfer is also in direct contact with the water surface, wrinkles are prone to occur, and when the object to be transferred is pressed into the water surface, water will flow and easily clump on the film. As a result, it is difficult to reliably perform hydraulic transfer on the surface of the object to be transferred.

Embodiment

[0096] Examples are shown below to describe the present invention more specifically, but the present invention is not limited thereto. Among them, examples are shown regarding the composition of a two-layer film for hydraulic transfer in which polyvinyl alcohol having a degree of polymerization of 2000 and a degree of saponification of 88 mol % as a print receiving layer is laminated on a substrate layer with a thickness of 30 μm.

[0097] (Evaluation of samples)

[0098] Surface Roughness Evaluation

[0099] In an environment of 23° C. and 50% RH, Ra and Rz were measured with a roughness meter (manufactured by Accretech: Handysurf E-35A). Gloss was measured with a gloss meter (manufactured by Nippon Denshoku Kogyo Co., Ltd.: Gloss Meter VG7000).

[0100] Peelability evaluation

[0101] The print-receiving layer made of PVA laminated on the A4 size base material was pulled and peeled by hand, and the peeling state was evaluated.

[0102] The detachability was classified in...

Abstract

Provided is a film for hydraulic transfer with which a high-resolution printed image, e.g., a photograph, can be transferred to a receiving object to obtain a transferred image having a smooth surface, without deteriorating the image quality. The film for hydraulic transfer is characterized by comprising at least two layers which are an ink-receiving layer and a base layer, the base layer having a surface roughness Ra of 0.40 [mu]m or less and a gloss of 80 or higher.

Description

technical field [0001] The present invention relates to a film for hydraulic transfer printing. Background technique [0002] Conventionally, a hydraulic transfer method has been known as a method of forming a printed pattern by transfer printing on the surface of a molded body having a three-dimensional surface formed of unevenness. Printing on a curved surface by hydraulic transfer printing is formed by floating a film for transfer having a printing layer constituting a pattern activated by an active agent on a water-soluble or water-swellable film so that the printed surface is Above, the transferred object to be drawn is pressed in from above, and the image of the printing layer is transferred to the outer peripheral surface of the transferred object by water pressure. Usually, hydraulic transfer printing is carried out in the range of water temperature 10-40°C. [0003] The accuracy of photographs and the like in the printing layer is expected, and a method of printin...
