  • Patent number: 5360696
    Abstract: This invention provides a process for producing a resist composition in which the content of relatively large undissolved particles is low just after production of the composition and the content of relatively large undissolved particles increases only to a small extent even if the composition is stored for a long period of time. Thus, this invention provides a process for producing a resist composition which comprises filtering a mixture of an alkali-soluble resin, a radiation-sensitive compound and a solvent by the use of a filter of which pore diameter is 0.1 .mu.m or below and of which particle-removing performance is 99% or above. Further, this invention provides also a resist composition comprising an alkali-soluble resin, a radiation-sensitive compound and an organic solvent not simultaneously having both acetoxy group and alkoxy group in its molecule, said composition containing undissolved particles having a particle diameter of 0.25 .mu.

  • Patent number: 5350661
    Abstract: In accordance with the present invention, there are provided water-developable photopolymerizable compositions useful for the preparation of printing plates. Printing plates prepared employing invention compositions have excellent form stability, thereby enabling such plates to be handled without the need for excessive care. Once photopolymerized, printing plates of the invention have excellent physical properties, enabling their use in many very demanding commercial applications, e.g., commercial flexographic printing. Such applications require the photopolymerized resin to have excellent water resistance (so that exposure to water-based inks does not significantly alter resin properties), as well as high durability (so that the physical contacting associated with the printing process does not significantly degrade resin properties).

  • Patent number: 5346810
    Abstract: Disclosed is a silver halide photographic material having a hydrophilic colloid layer which contains a dispersion of solid fine grains of an oxonole dye which does not have any dissociating proton-containing substituent or salt thereof capable of dissolving the dye during development, except the enolic proton constituting a part of the chromophoric group of the dye in the compound. In the photographic material, the oxonole dye colors only the specific hydrophilic layer without having any bad effect on the photographic properties of the material. The dye may be rapidly decolored by development of the material.
