The pretreatment agent for use before forming a coat by paint application of the present invention contains (A) one or more metal elements selected from a group consisting of zirconium, titanium and hafnium, (B) fluorine, (C) one or more coupling agents selected from an amino group-containing silane coupling agent, its hydrolyzate, and its polymer, and (D) a component of at least one of an allylamine and a polyallylamine, in which the ratio by mass of the coupling agent (C) to the component (D), (C/D) is 1 or more. The coating method by paint application of the present invention includes a chemical conversion treatment step of chemically treating a metal substrate with the pretreatment agent, and a step of forming a coat by paint application on the chemically-treated metal substrate. When a coating film is formed through forming a coat by paint application on the surface of a metal substrate that has been pretreated according to the present invention, the coating film can have excellent adhesion, salt water resistance and impact resistance.

Coating resin composition containing hydrolyzable organosilane, acrylic resin and polyorganosiloxane

The present invention provides a process for forming a hydrophilic inorganic coated film on a surface of a base material, the process comprising the steps of: (1) preparing an inorganic coating composition which contains, as a major component, a silicone resin obtained by hydrolyzing and condensation-polymerizing only the tetra-functional alkoxysilane represented by the formula: Si(OR),&lsqb;wherein R represents an alkyl group having carbon atoms up to and including 7 or an aryl group&rsqb;, and has a total solid content of not more than 5% by weight; (2) applying the inorganic coating composition to a surface of the base material to form a coated layer; and (3) drying and curing the coated layer to form a cured coated film having a thickness of 0.01 to 0.5 &mgr;m. The hydrophilic inorganic coated film formed by the process of the present invention is highly hydrophilic just after the film is formed, even in the case that it is not irradiated with ultraviolet rays.
