A lithographic printing plate precursor of direct image type, adequately prevented from occurrence of background stains and having excellent printing durability is provided, comprising a base and an image receptive layer provided on the base, in which the image receptive layer contains at least one of the following non-aqueous solvent-dispersed resin grains: Non-aqueous solvent-dispersed resin grains Polymer resin grains obtained by (1) subjecting to dispersion polymerization reaction in a non-aqueous solvent, a monofunctional monomer (A) being soluble in the non-aqueous solvent but insoluble after polymerization and containing at least one functional group capable of producing at least one polar group through decomposition and a monofunctional polymer [M] comprising a polymer principal chain containing at least recurring units each containing a silicon atom and/or fluorine atom-containing substituent, to only one end of which a polymerizable double bond group represented by the following General Formula (I) is bonded:
wherein V₀ is -O-, -COO-, -OCO-, -CH₂OCO-, -CH₂COO-, -SO₂-,
CONCHCOO- or CONHCONH-, (R₁ is a hydrogen atom or a hydrocarbon group containing 1 to 18 carbon atoms), and a₁ and a₂ are, same or different, hydrogen atoms, halogen atoms, cyano groups, hydrocarbon groups, -COO-R₂ or -COO-R₂ via a hydrocarbon group (R₂ is a hydrogen atom or optionally substituted hydrocarbon group).
摘要:
A non-aqueous dispersion polymer having a high solids content and substantial adhesive properties is prepared by copolymerizing a selected monomer with a polymeric monomer and a polar monomer in an organic diluent to produce an insoluble polymer dispersed in the organic phase.

摘要:
Inherently tacky infusible pressure-sensitive adhesive microspheres are prepared by polymerizing at least one monomer which when polymerized will form a pressure-sensitive adhesive having a glass transition temperature less than abotu -20 DEG C. in an organic medium in which the monomer is substantially insoluble and in the presence of a surfactant and a suspension stabilizer which are soluble in the organic medium and substantially insoluble in the monomer under conditions of shear sufficient to form suspended particles of a size less than 200 microns. A monomer soluble initiator is preferably employed. The preferred media are ethylene glycol and glycerol and the preferred monomers are 2-ethyl hexyl acrylate and methacrylic acid.
摘要:
Polymers are made by a novel form of precipitation polymerisation. The polymerisation is generally conducted in the presence of sufficient dispersion promoter for the precipitated polymer particles to be held as a stable dispersion in the reaction medium. The invention is of particular value for the production of associative polymers.
