| abstract | 1478334 Light-sensitive copying material FUJI PHOTO FILM CO Ltd 28 May 1974 [29 May 1973] 01792/77 Divided out of 1478333 Heading G2C A light-sensitive copying material has coated on a support, in the following order, a light-sensitive layer which comprises an o-quinone diazide compound that becomes more soluble in an alkaline developer medium upon irradiation with active rays, and a light-insensitive layer comprising a water-insoluble organic resin selected from a styrene/ maleic anhydride copolymer, a styrene/acrylic acid copolymer, polyvinyl butyral or shellac, which resin is barely soluble in, but is permeable to, the alkaline developer medium, the material having no further light-sensitive layer comprising an o-quinone diazide compound coated on the light-insensitive layer. The o-quinone diazide compounds illustrated comprise esters of aromatic polyhydroxy compounds, including the condensation product from acetone and pyrogallol, and an o-quinone diazide sulphonic acid. The o-quinone diazide compound may be mixed with a resin e.g. a phenol or cresol resin, a styrene/maleic anhydride copolymer or shellac, or p-phenyl or p-t-butylphenol formaldehyde resins or polyvinyl butyral. The resin layers may contain o-quinone diazide compound provided that it does not render them light-sensitive. The layers may include dyes, pigments, fillers, e.g. TiO 2 , clay. Suitable developers are aqueous solutions of organic alkalies or basic solvents such as mono- or diethanolamine, propanolamine or morpholine and may contain propyl alcohol or sodium lauryl sulphate. |
