Problems solved by technology

[0009] In addition, in Figure 5 In the transfer material with the structure shown in , although it is desired to improve the surface strength of the transfer molded product, the ionizing radiation curing resin is used as the release layer 109, but because if the ionizing radiation curing resin is partially patterned by the printing method On the other hand, there is a problem that sufficient surface strength cannot be obtained because its thickness is limited.

Embodiment 1

[0070] Using a polyethylene terephthalate film with a thickness of 38 μm as the substrate, coat the release layer in a strip pattern and allow it to fully cure, then form an ionizing radiation curing layer on the entire surface, and then form the release layer in sequence A reinforcement layer, a pattern layer, and an adhesive layer are partially formed on the parts to obtain a transfer material.

[0071] Using the transfer material obtained in this way, when acrylic resin is used as the molding resin for decoration and simultaneous molding, the sprue that is in contact with the part where the release layer is not provided can be smoothly peeled off from the transfer material and has high surface strength. Formed products.

Embodiment 2

[0073] Using a polyethylene terephthalate film with a thickness of 38 μm as the substrate, coat the release layer in a strip pattern and allow it to be fully cured, then form an ionizing radiation curing layer and a reinforcement layer in sequence, and then in turn A pattern layer and an adhesive layer were partially formed on the site where the mold release layer was formed, and a transfer material was obtained.

[0074] Using the transfer material obtained in this way, when acrylic resin is used as the molding resin for decoration and simultaneous molding, the sprue that is in contact with the part where the release layer is not provided can be smoothly peeled off from the transfer material and has high surface strength. Formed products.

[0075] Since the present invention is composed of the above configurations, it has the following effects.

[0076] In the transfer printing material of the present invention, since the strip-shaped pattern release layer is laminated on th...

Abstract

A transfer material comprising a substrate sheet (2, 52), strip-pattern mold release layers (3, 53) laid on the substrate sheet, an ionizing radiation curing layer (4, 54) entirely laid on the mold release layers, pattern layers (5, 55) laid entirely or partially on the ionizing radiation curing layer, and adhesive layers (6, 56) laid partially on the pattern layers at portions only that overlap the mold release layers.

Description

technical field [0001] The present invention relates to a transfer material used for decorating the surface of a resin molded article. Background technique [0002] Conventionally, as a method of decorating the surface of a resin molded product, there is a molding simultaneous transfer method. The so-called molding simultaneous transfer method is to sandwich the transfer material with the transfer layer consisting of a peeling layer, a pattern layer, an adhesive layer, etc. on the substrate in sequence, into the forming metal mold, so that the resin is injected to fill the cavity, A method of adhering a transfer material to the surface of a resin molded product while cooling it, then peeling off the base sheet, and transferring the transfer layer to the surface of the resin molded product for decoration. [0003] Usually, the transfer material used in the forming simultaneous transfer method is printed on a long substrate according to the roll width of the printing machine ...
