Abstract

PURPOSE: To prevent corrosion due to the carrier fluid of a liquid developer and thereby to enable formation of sharp images, by using a specified phenolic resin for the main component of the recording layer of a printing original form forming a toner image.
CONSTITUTION: On a conductive substrate having a hydrophilic surface a recording layer is formed prepared by using as a main component a phenolic resin having repeating units of the formula and by dispersing a photoconductor, esp. a phthalocyanine type pigment. On this recording layer a static latent imge is formed and then, a toner image is formed with a liquid developer. Subsequently, the recording layer in the area free of the toner image is dissolved off with an alkaline solution to form a printing form. In the formula, R1 and R2 are H or lower alkyl; R3WR5 are H, halogen, OH, nitro, amino, carboxy(salt), sulfo(salt), a 1W20C chain hydrocarbon group, or 4W14C cyclic hydrocarbon group; and when one or more of R3WR5 are a 4 or more C substituted group, one or more of them are a hydrophilic functional group or have such a group.
