Definitions

  • the invention relates to a method for preserving ready-to-print planographic printing forms in order to protect the plates during storage from being used for printing against the ingress of air and dirt and at the same time to permanently hydrophilize their non-printing surface areas.
  • FR-A 2 350 209 also mentions dextrins as a water-soluble film-forming component in preservative treatment solutions for printing forms, but apart from that they contain not only water as a solvent, but also also a petroleum fraction, glycerin and a surfactant.
  • a solution of. was placed on a 300 J.Lm thick substrate made of electrolytically roughened and anodized aluminum applied and dried to a uniform photoconductor layer with a weight of 5 g / m 2 .

Claims (4)

1. Procédé de conservation de formes pour impression planographique comportant un matériau de support à base d'aluminium développées de façon à être prêtes à l'impression, dans lequel la forme pour impression planographique est traitée avec une solution aqueuse d'un composé organique de masse moléculaire élevée filmogène soluble dans l'eau et d'un acide hydrophilisant et, après ce traitement, est séchée, caractérisé en ce que l'on emploie comme acide hydrophilisant un acide phosphonique organique, ce procédé excluant les formes pour impression planographique constituées de plaques d'impression à couches photosensibles fonctionnant comme positif et contenant des o-quinonediazides, qui, après le développement, sont chauffées à une température supérieure à 180 °C et ensuite sont conservées avec une solution aqueuse contenant 0,01 à 50 % en poids d'acide polyvinylphosphonique et de lâ gomme arabique ou de l'alcool polyvinylique.
2. Procédé selon la revendication 1, caractérisé en ce que l'acide phosphonique organique est l'acide polyvinylphosphonique.
3. Procédé selon la revendication 1, caractérisé en ce que l'on emploie l'acide phosphonique organique à une concentration de 0,05 à 10 % en poids par rapport au total de la solution.
4. Procédé selon la revendication 1, caractérisé en ce que l'on emploie comme composé organique de masse moléculaire élevée soluble dans l'eau de la gomme arabique, de la dextrine ou de l'alcool polyvinylique.
