Problems solved by technology

The problem with existing protective coatings is that they use acrylic or polyurethane-based coatings that have adhesion to ABS resins, acrylic resins, polycarbonate resins, etc., but they are very low in polarity and difficult to adhere to polypropylene-based coatings. Adhesion of the resin is insufficient, and its adhesion force decreases over time or due to heat, light, temperature, etc.
Therefore, the above-mentioned technology must form a protective coating film through an intermediate coating film

Embodiment

[0118] Hereinafter, the present invention will be described by way of examples, but the present invention is not limited to these examples.

[0119] (Manufacture of hydroxyl-containing resin composition (P), Examples 1-2, Reference Examples 1-8)

[0120] In a four-necked flask with a volume of 1 liter equipped with a stirrer, a cooler, a thermometer, and a monomer instillation device, add the component (A) according to the composition shown in Table 1, and heat up to an internal temperature of 85°C while stirring. 85°C was maintained for 20 minutes. Then, component (B) was instilled over 2 hours, and after completion of instillation, component (C) was added and polymerized at 85° C. for 2 hours to obtain a solution of a hydroxyl group-containing resin composition (P). This solution was further diluted with toluene. It should be noted that in Table 1, the amount of each component is expressed in parts by weight.

[0121] To the solution obtained by diluting the obtained hydr...

Abstract

A coating composition for protecting a pattern layer for hydraulic transfer which uses, onto a transfer formed product obtained by the hydraulic transfer of a pattern layer having been formed through printing or application on a film base material being soluble in or swelling with water onto a polypropylene based resin formed article, a protective coating having adhesiveness to both of said polypropylene based resin formed article and said pattern layer, wherein use is made of a protective coating film obtained by curing a hydroxyl group containing resin composition (P) prepared by subjecting a resin component (A) comprising a chlorinated polypropylene based resin and a poly-ol component (B) comprising an acryl polyol selected among cyclohexyl methacrylate, t-butyl methacrylate, styrene and hydroxyethyl methacrylate to a graft polymerization, with a polyisocyanate based curing agent (Q).

Description

technical field [0001] The present invention relates to a coating composition, a decorative molded article protected by the coating composition, and a manufacturing method thereof. The coating composition is a water-soluble or swellable film on a polypropylene resin molded article The pattern layer formed by printing or coating on the base material is subjected to hydraulic transfer, and the resulting transferred molded article has excellent adhesion to both the polypropylene resin molded article and the pattern layer. permanent protective coating. [0002] this application claims the priority based on Japanese Patent Application No. 2004-282562 for which it applied to Japan Patent Office on September 28, 2004, and uses the content here. Background technique [0003] Recently, in order to decorate various patterns such as moiré and checkered patterns on resin molded products having complicated surface shapes, a hydraulic transfer method is used. In this method, a transfer ...
