Problems solved by technology

[0004] However, in Patent Document 1, when a conductive pattern is formed on a cured coating film having insulating properties by further using a dispersion liquid containing a conductive component such as an aqueous dispersion liquid containing PEDOT (polythiophene-based conductive polymer), the cured coating film The surface part of the film is hydrophobic, so the wettability of the dispersion liquid containing conductive components such as the aqueous dispersion liquid containing PEDOT (polythiophene conductive polymer) is not sufficient
That is, when an aqueous dispersion containing PEDOT or the like is used to form a conductive pattern, there is a problem that the above-mentioned aqueous dispersion containing PEDOT, etc. is repelled on the cured coating film, making it difficult to form a desired conductive pattern.

[0060] The components shown in the following Table 1 were mixed according to the compounding ratio shown in the following Table 1, and mixed and dispersed by ultrasonic stirring (manufactured by AS ONE Corporation, "US CLEANER model USK-2R") , The photosensitive composition used in Examples 1-8 and Comparative Examples 1-5 was prepared. Then, the prepared photosensitive composition was coated as follows, and the test piece which has a cured coating film was produced. In addition, the numerical value of the compounding ratio in Table 1 represents a mass part, and the blank part of a compounding ratio means 0 mass part.

Abstract

The invention provides a photosensitive composition. The photosensitive composition has no damage on the sealing performance and electric insulation performance of circuit substrates, has excellent wettability on the conductive component contained dispersed solution such as the aqueous dispersion including the PEDOT (polythiophene-based conductive polymer), and can reduce the contact angle of the PEDOT aqueous dispersion on a curing coat. The photosensitive composition includes (A) (methyl) acrylate monomers, (B) a photopolymerization initiator, and (C) a compound having an acid group but having no olefin unsaturated group. The solid acid value of the photosensitive composition prepared from the compound having the acid group but having no olefin unsaturated group is 0.20-5.0 mgKOH/g.

Description

technical field [0001] The present invention is a photosensitive composition for forming an insulating film on a substrate. For example, it relates to a method for using a water-dispersed composition containing PEDOT (polythiophene-based conductive polymer) on a cured coating film of the photosensitive composition of the present invention. A photosensitive composition in which a conductive pattern is formed from a dispersion liquid containing a conductive component such as a liquid. Background technique [0002] As the circuit board, for example, a substrate having a polyethylene terephthalate film (PET film), a polyimide film or a polyester film, or a glass substrate with an ITO (indium tin oxide) film formed on it and etched A circuit board with a circuit formed by patterning an ITO film into a desired shape; a circuit board with a predetermined circuit pattern formed by etching a conductor such as copper foil on a substrate. In order to form an insulating coating on this...
