摘要： An image forming material and an image forming method which are capable of accommodating a direct laser drawing method, producing an image of a high resolution easily and performing an image forming operation easily in a bright room, lithographic printing plate manufacturing method and apparatus, a lithographic printing plate making method, and a printed wiring board manufacturing method are provided. Concretely speaking, an image forming material having a layer of thermally meltable fine particles on a base material, and a method of forming an image on a base material by melt-fixing the portion of a layer of the thermally meltable fine particles of the image forming material which corresponds to an image portion, and then removing the portion of the layer of thermally meltable fine paticles which corresponds to a non-image portion are provided. The layer of thermally meltable fine particles can be melt-fixed by a laser. The removing of the non-image portion of the layer of thermally meltable fine particles can be done more easily by providing a layer of an alkali-soluble resin between the base material and the layer of thermally meltable fine particles, and applying an alkali solution to this layer of an alkali-soluble resin.

摘要： Production of a printed circuit board comprises illumination through a resist pattern of a conductive board having at least one photoconductive layer, whose chargeability is altered by illumination, formation of an electrostatic latent image, production of a toner image, removal of excess toner to form a resist and removal of the areas of the bare metallic layer by etching. A process for the production of a printed circuit board (I) comprises: (A) illumination through a resist pattern of a conductive board having at least one photoconductive layer, whose chargeability is altered by illumination, on a surface of a conductive support that comprises an insulating substrate having a conductive metallic layer on at least one surface; (B) charging of the photoconductive layer to form an electrostatic latent image; (C) production of a toner image on the photoconductive layer by a toner development treatment; (D) removal of the areas of the photoconductive layer to which no toner is adhered by dissolution to form a resist image; and (E) removal of the areas of the conductive metallic layer by etching outside of the areas where the resist image is formed.

摘要： PURPOSE:To enhance the adhesion of materials even at the time of including an image forming layer having low adhesiveness and a non-photosensitive resist layer in the material by providing an intermediate layer as the undercoat layer of the non-photosensitive resist layer between them. CONSTITUTION:This material is formed by laminating a non-photosensitive resist layer and a photosensitive silver halide gelatin emulsion layer in that order on an image forming layer of the substrate which has an image forming layer(s) on its one side or both sides. At this time, an intermediate layer is interposed between the image forming layer and the non-photosensitive resist layer. As the resin used for the intermediate layer, polyvinyl alcohol is most desirable. Various kinds of polyvinyl alcohol are used as this polyvinyl alcohol depending on their molecular weight, degrees of saponification, etc. The suitable kinds of polyvinyl alcohol, alone or as a mixture of at least two kinds selected from among them, can be used for this purpose. Examples of this polyvinyl alcohol are PVA-117, PVA-217, etc. At the time of forming the intermediate layer, optionally, a surfactant, etc., are mixed into the coating fluid to uniformly coat the substrate.
