Embodiment

[0125] [Manufacture of a polymer comprising γ-methacryloxypropylhepta(trifluoropropyl)-T8-silsesquioxane unit as an example of component (b1)]

[0126] First, γ-methacryloxypropylhepta(trifluoropropyl)-T8-silsesquioxane was synthesized by the following procedure. Put trifluoropropyltrimethoxysilane (100g), tetrahydrofuran (tetrahydrofuran, THF) (500mL), deionized water (10.5 mL) into a four-necked flask with an inner volume of 1L equipped with a reflux cooler, a thermometer, and a dropping funnel. g), and sodium hydroxide (7.9 g), while stirring with a magnetic stirrer, heated from room temperature to THF reflux temperature through an oil bath. Stirring was continued for 5 hours from reflux to complete the reaction. Thereafter, the flask was pulled up from the oil bath, left to stand overnight at room temperature, placed in the oil bath again, and heated and concentrated at a constant pressure until solids were precipitated.

[0127] The precipitated product was collected by...

Abstract

[Problem] To provide a coating film which is capable of maintaining good water repellency and antifouling properties. [Solution] A photopolymerizable coating composition which contains, as photopolymerizable components, a urethane (meth)acrylate (component (a)) and a photopolymerizable (meth)acrylic compound (component (b)), and which is configured such that: from 1% by weight to 50% by weight (inclusive) of the component (a) and from 50% by weight to 99% by weight (inclusive) of the component (b) relative to the total amount of the photopolymerizable components are mixed; and the component (b) contains a photopolymerizable acrylic compound (component (b1)) which has a structural unit derived from a fluorosilsesquioxane derivative represented by formula (1), a reactive silicone (component(b2)) and a photopolymerizable acrylic compound (component (b3)) which has no urethane unit, no fluorine atom and no Si atom.

Description

technical field [0001] The present invention relates to a coating liquid that can be used as a top coat of various articles, especially as a material for laminated films such as paint protection films. Background technique [0002] Paint Protection Film (PPF) is a film-like product that can be used in the surface protection of industrial products that can be used outdoors. The basic structure of PPF is a laminate comprising at least two layers of a base material including a flexible and transparent resin film and an adhesive layer. Moreover, PPF is generally supplied on the market in the state of a laminated film that further has a coating layer for improving the antifouling performance or scratch resistance of the substrate on the side of the substrate opposite to the adhesive layer. , and a release layer is further provided on the side of the adhesive layer opposite to the substrate. When using PPF, first cut the PPF according to the surface of the industrial product to ...
