Abstract

La presente invención se refiere a una composición de capa protectora positiva, caracterizada porque comprende una resina soluble en álcali y, cono un sensibilizador, un ester de ácido quinondiazida sulfónico de un compuesto de fenol de la fórmula: en donde Y1, Y2, Z1, Z2, Z3, Z4, Z5, Z6, y Z7 son independientemente un átomo de hidrógeno, un grupo hidroxilo, o un grupo alquilo de 1 a 4 átomos de carbono, que puede estar sustituido con un átomo de halógeno, siempre y que al menos uno de Y1 y Y2 sea un grupo hidroxilo, y al menos dos de Z1 a Z7 sean grupos hidroxilo, y R1, R2, R3, R4, R5, R6, R7, R8, y R9 son independientemente un átomo de hidrógeno, un grupo alquenilo de 2 a 4 átomos de carbono, un grupo cicloalquilo o un grupo arilo.The present invention relates to a positive protective layer composition, characterized in that it comprises an alkali-soluble resin and, as a sensitizer, a quinondiazide sulfonic acid ester of a phenol compound of the formula: wherein Y1, Y2, Z1, Z2, Z3, Z4, Z5, Z6, and Z7 are independently a hydrogen atom, a hydroxyl group, or an alkyl group of 1 to 4 carbon atoms, which may be substituted with a halogen atom, provided that at least one of Y1 and Y2 is a hydroxyl group, and at least two of Z1 to Z7 are hydroxyl groups, and R1, R2, R3, R4, R5, R6, R7, R8, and R9 are independently a hydrogen atom, a group alkenyl of 2 to 4 carbon atoms, a cycloalkyl group or an aryl group.
