摘要:
This invention is directed to the reaction product of an O-epoxyalkylated tetrakis (hydroxyphenyl) alkane resin with a phenol, which is used either as an upper layer over a lower layer of a diazo resin in a bi-layer system or as a homogeneous mixture with a diazo resin in a mono-layer system to provide a water-developable, negative-working, lithographic printing plate.
摘要:
A photosensitive composition capable of producing a photosensitive lithographic printing plate having excellent developing property and press life in direct lithoprinting even if stored in an atmosphere having high temperature and humidity. The photosensitive composition comprising a diazo resin (a) wherein a counter anion is an inorganic acid anion or an aliphatic organic acid anion having 3 or less carbon atoms; a diazo resin (b) wherein a counter anion is an aliphatic or aromatic organic acid anion having 6 or more carbon atoms; and a polyurethane resin which is a reaction product of an isocyanate comprising 40 to 90 mol% of a diisocyanate represented by the general formula (I) defined hereinabove based on the amount of total isocyanate components with an alcohol comprising 30 to 90 mol% of a diol represented by the general formula (II) defined hereinaove based on the amount of total alcohol components.
摘要:
L'invention concerne des compositions photopolymérisables filmogènes oléophiles et développables à l'eau. Lesdites compositions comportent un produit de réaction photosensible tel que le paradiazodiphénylamine condensé formaldehyde couplé avec un acide arylsulfonique et une résine époxy fluide à température ambiante. Lesdites compositions sont plus particulièrement destinées à la réalisation de plaques lithographiques ayant la propriété de se développer à l'eau tout en ayant une très grande résistance mécanique et permettant un nombre élevé de tirages.
摘要:
A photosensitive composition that can give a coating film having excellent solvent resistance and excellent wear resistance, and provide a photosensitive planographic printing plate having excellent solvent resistance, particularly resistance to a UV ink-washing oil used in UV ink printing, and excellent press-life is disclosed. The photosensitive composition contains a resin having a barbituric acid group in the side chain. A photosensitive planographic printing plate comprising a support and a photosensitive layer comprising the photosensitive composition on the surface of the support is also disclosed.
