Embodiment 1

[0029] A polyester resin mold (TORAY company product: XM80) was used for the bottom mold, and an unsaturated urethane-based profiled layer was gravure-coated with a thickness of 0.5 μm on the bottom mold.

[0030]Then, acrylic urethane resin (SARTOMER company product: CN953) 48 parts by weight, butyl ethylene acrylate 25 parts by weight, stearyl methacrylate (SARTOMER company product SR324) 22 parts by weight and Allyl methacrylate (SARTOMER company product SR201) 5 parts by weight is used for ultraviolet curable resin, 4 parts by weight of cumene hydroperoxide is used for thermosetting initiator, 2-hydroxyl-2-methyl- 1-phenyl-1-acetone (Ciba Specialty Chemical Company product: Darocur-1173) 4 parts by weight is used for photopolymerization initiator, and uses other dispersant (BYK company product: ANTI-TERA-YOU) 2 parts by weight Several preparations of protective layer coating solution. The protective layer coating liquid was coated on the deformed layer with a thickness of...

Embodiment 2

[0033] In Example 1, instead of using cumene hydroperoxide as a thermosetting initiator, 4 parts by weight of dibenzoyl peroxide was used to prepare a coating solution for a protective layer. Except for this, a transcription film (B) for in-mold injection was manufactured in the same manner as in Example 1 above.

Abstract

The present invention relates to a production method for an in-mould, semi-cured transfer film. More specifically, it relates to a production method for an in-mould, semi-cured transfer film which has a laminated structure comprising, in sequence on a base film: a mould-release layer and a protective layer, a print layer, a vapour-deposited layer and an adhesive layer. The said transfer film doesnot produce harmful substances such as formaldehyde (HCHO) during the production process, and can endow injection moulded articles with highly outstanding physical properties when it is used.

Description

technical field [0001] The invention relates to a method for manufacturing an in-mold semi-hardened transcription film. Background technique [0002] Recently, in-mold injection molding is widely used in the manufacture of front panels of various home appliances such as washing machines and air conditioners, and liquid crystal display windows of computers and mobile phones. As we all know, the in-mold injection molding method refers to the method of injecting molten resin in the state where a transcription film printed with a given pattern is installed between the fixed frame and the movable frame of the injection mold. This in-mold injection molding method solves the problem of 360-degree surround transcription and concave-convex part transcription that cannot be solved by the previous thermal transcription method, and simplifies the four-step process consisting of injection molding, vacuum deposition, adhesion and pasting of aluminum plates into injection molding. And tra...
