Problems solved by technology

However, since the surface to be released from the release film (plastic film having a release layer) used for the transfer film has a high surface tension, it is difficult for the antifouling effect of the laminate to be transferred on the base material. Although the hydrophobic performance is excellent, the oleophobic performance is not sufficient

[0271] [Manufacture Example 1] Manufacture of hydrolysis-treated and condensation-reaction-treated silica gel (1)

[0272] 63 g of Sul-ria S was placed in a 4-necked flask reaction vessel equipped with a stirrer and a condenser, and then 12 g of KBM503 was added. Thereafter, 4.4 g of water and 0.1 g of an aqueous 0.01 mol / l hydrochloric acid solution were sequentially added with stirring, and heated at 80° C. for 2 hours. Next, the reaction system was brought into a reduced pressure state, and the volatile components were distilled off until the solid content concentration became 40%, and then 38 g of toluene was added thereto, followed by heating at 80° C. for 2 hours. Then, the reaction system was put in a reduced pressure state, and the volatile components were distilled off to a solid content concentration of 60%, and further heated at 80° C. for 2 hours to prepare a hydrolysis-treated and condensation-reaction-treated silica gel (1).

Abstract

Disclosed is a transfer film which uses a film having high surface tension and is provided with an antifouling layer by a wet process, and on which a functional layer such as an antireflection layer can be laminated. The transfer film is capable of providing a laminate that has excellent water repellency, oil repellency, transparency, abrasion resistance and perspiration resistance. Also disclosed is a method for producing the transfer film. Specifically disclosed is a transfer film which is obtained by laminating an antifouling cured film on the surface of a transparent base film. The transfer film is characterized in that the water contact angle (1) of a surface of the antifouling cured film, said surface being not in contact with the transparent base film, is 100 DEG or less, the water contact angle (2) of a surface of the antifouling cured film, said surface being in contact with the transparent base film, is 90 DEG or more, and the contact angle (a) thereof with triolein is 55 DEG or more.

Description

technical field [0001] The present invention relates to a transfer film, a resin laminate, and methods for producing them. Background technique [0002] Transparent resins such as acrylic resins and polycarbonate resins are widely used in various materials such as industrial materials and construction materials. Especially in recent years, due to its transparency and impact resistance, it has been used as front panels of various displays such as CRTs, liquid crystal televisions, and plasma displays. [0003] In recent years, various functions have been required for front panels. For example, one of the required functions is anti-reflection function. The anti-reflection function is a function to reduce the reflected light from indoor fluorescent lamps on the front panel to make the image display more vivid. As a method of imparting an antireflection function, for example, there is a method of forming an antireflection layer on the surface of the front panel. In addition, ...
