摘要

COMPOSITION OF A PROTECTIVE LAYER OF THE LIGHT THAT ACTES POSITIVE (e.g., A DRY FILM IN MONOCAPA) THAT IS REMOVABLE IN ALCALINE AQUAIN SOLUTION, COMPOSED OF A PHOTOACED GENERATOR AND A UV-RESISTANT BINDING SYSTEM, WHICH PERMITS A FOT EFFICIENT OF THE PHOTOACTIVE COMPONENT. A CELLULOSIC RESIN WITH AN ACID FUNCTIONAL GROUP MAY BE THE ONLY BINDING RESIN, EVEN IF OPTIONALLY AN ACCILICAL ACID RESIN CAN BE USED. DRY COATING IS FLEXIBLE AND CAN BE USED AS A LAYER OF PROTECTION IN PROCESSES OF AGUAFUERTE AND PLAQUEADO.
