Abstract

PURPOSE:To obtain an image forming composition having superior work efficiency and suitable for multiple exposure by using a reducing dye as an optical coupler and an optical activator contg. an onium salt of a VIb group element so as to prevent reduction in sensitivity which is due to the color development of a dye and causes longer exposure time. CONSTITUTION:A reducing dye (A) such as methyl capryl blue as an optical coupler and an optical activator (B) contg. an onium salt of a VIb group element represented by a general formula [R1R2R3VIb]<+>[MXn]<-> (where each of R1-R3 is aryl, VIb is a VIb group element selected among S, Se and Te, and X is halogen) are added to an image forming composition consisting of a polymer binder (C), a photopolymerizable monomer or oligomer (D) such as pentaerythritol acrylate or polyethylene glycol diacrylate, and a photopolymn. initiator (E) such as benzophenon. The activator (B) and the initiator (E) absorb light in different wavelength ranges. The dye (A) develops color when oxidized by the activator (B).

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photopolymerizable image forming composition. The material coated on the substrate is exposed to light through a negative image, etc., and the areas exposed to the light polymerize or crosslink, making them insoluble in solvents, and the areas not exposed to light are eluted, creating an image on the substrate. It is known to form 5, and this principle is applied to the production of plate materials and printed wiring boards.

For example, in the method disclosed in Japanese Patent Publication No. 48-38403, a leuco dye is mixed in a composition prepared by adding imidazolyl and P-aminophenyl ketone to an ethylene monomer, but it is generally used as a light source. When coloring a composition using an ultraviolet light source such as a high-pressure mercury lamp, the photopolymerization or crosslinking rate decreases due to the presence of the dye, so the exposure time must be lengthened. This creates the disadvantages of having to do so.

This is presumed to be due to the fact that the light energy absorbed by the photopolymerization initiator and the like is divided and used for both photopolymerization or crosslinking and color development of the dye.

These Group Ⅲb onicum salts are selected to have a light absorption wavelength range different from that of the photopolymerization initiator described above, but the difference in the light absorption wavelength range between the two is generally determined by the highest absorption spectrum. The difference in wavelength showing the peak is about 20 nm or more. However, the difference between the M peaks of the absorption spectra of the original activator and the photopolymerization initiator may be 10 nm, and conversely, if the distributions of both are wide, the difference is, for example, 50 nm or more. Considering the wavelength and distribution of the peak, the source of the wavelength mainly absorbed and utilized by the former polymerization initiator -9= activates the original activator to act as an oxidizing agent and oxidizes the reduced dye. The difference in the wavelength range is used for color development and substantially inhibits polymerization and curing of the composition.

90 millijoules (
mj)/cd exposure was performed. The exposure time was 20 seconds. After exposure, the polyethylene terephthalate film support was peeled off, the exposed layer was immersed in chloroethane (1.1.1-t'), developed, and the unexposed areas were removed) and dried. In the test negative image, a 9-step image remained on the copper coated glass fiber reinforced epoxy/resin board, and the resolution of the printed wiring image was 50 μm.

Furthermore, before the development, the unexposed area was colorless, the exposed area was clearly colored purple, and the color absorbance 0.5 contrast was clear and sufficient for conducting an exposure test. Furthermore, after this exposure, the circuit was left to stand day and night, and the next day it was developed and etched, and the film was removed to form a printed circuit.
This was convenient for inspecting the state of membrane removal.

[Example 2] Rhodamine lactam was used instead of crystal violet lactone as a reduced dye, and di-diphenyl 2,5-sulfonic acid was used instead of triphenylsulfonicum hexafluoroarsenate as a group ylb onium salt type activator. The test negative image, the negative image for printed wiring were developed, and the printed wiring was formed in the same manner as in Example 1 except that methylphenylsulfonicum hexafluoroarsenate was used.
