Abstract

PURPOSE:To obtain the title composition which forms a conductive coating film excellent in conductivity, transparency, solvent resistance and marring resistance by mixing a silicic acid of a specified formula, a mixture obtained by dispersing an Sb-doped tin oxide powder with a silane coupling agent, a photosensitizer, and a solvent. CONSTITUTION:A silicic acid of the formula (wherein n is 3 to 6) is mixed with a mixture obtained by dispersing an Sb-doped tin oxide powder having a particle diameter of 0.2mum or smaller with a silane coupling agent (e.g. gamma- methacryloxypropyltrimethoxysilane), a photosensitizer (e.g. benzil dimethyl ketal) and a solvent (e.g. methyl ethyl ketone) to give the title composition. A coating film excellent in conductivity, transparency, solvent resistance, marring resistance and pencil hardness can be formed by the ultraviolet curing of this composition.

2. Description of the Related Art In recent years, a conductive coating film has been formed on a glass surface of a cathode ray tube of a television or a display of various OA devices for the purpose of preventing static electricity. This method includes a method of applying an organic substance such as a hydroxyl group-containing polymer, a higher alcohol, and a surfactant, but this method has poor solvent resistance and scratch resistance, and therefore has a short life of antistatic effect and is not practical. . As another method, formation of an antistatic film using an inorganic material has been attempted. For example, JP-A-62-187188 discloses a method in which a hydrolyzable tin compound or antimony-doped tin compound is hydrolyzed to obtain fine particles, water is removed, and the particles are dispersed in ethanol and baked. ing. However, this method has a drawback that it is inferior in scratch resistance because it does not contain a binder. Japanese Unexamined Patent Publication (Kokai) No. 62-252481 discloses a composition comprising a conductive powder, a binder and a solvent, but the binder is an organic type, so that the scratch resistance is limited.
Japanese Unexamined Patent Application Publication No. 1-29887 discloses tin oxide fine particles,
An antistatic treatment liquid consisting of silica sol and an organic solvent is disclosed, but since this liquid is a heat-curing type, it is necessary to heat the entire CRT in order to completely cure the thin antistatic film on the surface of the CRT. It is not desirable in efficiency, and it takes a lot of time for heating and cooling.

The conductive coating composition of the present invention has a solid content of 0.1.
It is preferably in the range of 10% by weight. If it is less than 0.1% by weight, the resistance reduction is insufficient, and if it exceeds 10% by weight, the scratch resistance tends to be lowered. The solvent of the component (D) is preferably blended so that the solid content of the composition is 0.1 to 10% by weight. The photosensitizer as the component (C) is preferably used in an amount of 0.1 to 10 parts by weight based on 100 parts by weight of the silane coupling agent as the component (B).
If it is less than 0.1 part by weight, the photocurability tends to be low, and if it exceeds 10 parts by weight, the scratch resistance tends to be low. When the antimony-doped tin oxide powder as the component (B) is dispersed with a silane coupling agent, the compounding ratio is 100 silane coupling agent.
Antimony-doped tin oxide is 50 to 20 parts by weight.
A range of 00 parts by weight is preferred. Outside of this range, roll dispersion is difficult. Next, the compounding ratio of the silicic acid as the component (A), the antimony-doped tin acid powder as the component (B), and the silane coupling agent will be described. Antimony-doped tin oxide powder is 10-4 with respect to 100 parts by weight of silicic acid.
It is preferably used in the range of 00 parts by weight. If it is less than 10 parts by weight, the resistance reduction is insufficient, and if it exceeds 400 parts by weight, the scratch resistance tends to decrease. The compounding ratio of the silane coupling agent is preferably in the range of 0.1 to 200 parts by weight with respect to 100 parts by weight of the total of silicic acid and antimony-doped tin acid powder. If it is less than 0.1 part by weight, the curability tends to decrease, and if it exceeds 200 parts by weight, the scratch resistance tends to decrease. Dispersion of the antimony-doped tin oxide powder with a silane coupling agent is preferably roll dispersion with a strong shearing force, but dispersion with a bead mill such as a sand grinder is also possible. When a dispersion liquid of antimony-doped tin oxide powder and a silane coupling agent is dispersed in silicic acid and a solvent, a usual dispersion method such as bead milling or ultrasonic dispersion can be applied.

A conductive coating film is obtained by irradiating ultraviolet rays with a general ultraviolet ray irradiating device such as a metal halide lamp and curing. It can be cured by heating, but UV curing can be performed at low temperature for a short time. The treated film thickness is preferably 40 μm or less from the viewpoint of crack resistance.

Example 1 50 parts of T-1 (trade name of antimony-doped tin oxide powder manufactured by Mitsubishi Materials Corp., antimony doping amount of 10%, primary particle size of about 0.05 μm), 25 parts of diacetone alcohol, and A mixture of 25 parts of γ-methacryloxypropyltrimethoxysilane was passed through a triple roll three times to obtain a dispersion mixture. 1 part of this mixture, 30 parts of silicic acid solution A, 0.003 parts of benzyl dimethyl ketal, 69 parts of methyl ethyl ketone were added to a bead mill (zirconia beads 0.5 mm
φ) was mixed and stirred to obtain a composition A. This was spin-coated on a glass substrate at 300 rpm for 30 seconds and then irradiated with an ultrahigh pressure mercury lamp at an exposure illuminance of 30 mW / cm 2 for 15 minutes to be cured to obtain a conductive coating film. Example 2 A conductive coating film was obtained in the same manner as in Example 1 except that γ-methacryloxypropyltrimethoxysilane was changed to vinyltriethoxysilane. Comparative Example 1 A composition obtained by removing benzyl dimethyl ketal from Composition A was spin-coated in the same manner as in Example 1 and then cured at 160 ° C. for 30 minutes to obtain a conductive coating film. Comparative Example 2 30 parts of silicic acid solution A, 0.7 parts of T-1 and 69 parts of methyl ethyl ketone were bead milled (zirconia beads 0.5 m
Composition B was obtained by mixing and stirring with mφ). From this, a conductive coating film was obtained by the same curing method as in Example 1. The obtained conductive coating film was evaluated for surface resistance, transmittance at 550 nm, pencil hardness and ethyl alcohol resistance. The results are shown in Table 1.
