Title
(EN) CLEAVABLE POLYMERS AND PHOTOGRAPHIC PRODUCTS AND PROCESSES EMPLOYING SAME
(FR) POLYMERES CLIVABLES ET PRODUITS PHOTOGRAPHIQUES ET PROCEDE LES UTILISANT
Abstract
(EN) Polymers comprising recurring units which, in the presence of silver ion or silver complex, are capable of undergoing cleavage or which, in the presence of an oxidizing or reducing agent, form a reaction product capable of undergoing cleavage so as to release a monovalent radical from the polymer. In a preferred embodiment, the released material comprises a photographically useful moiety. The invention also relates to photographic products and processes employing polymers comprising recurring units which, in the presence of a cleavage-initiating agent provided in an imagewise distribution as a result of development of a silver halide emulsion, undergo cleavage to release a correspondingly imagewise distribution of a photographically useful moiety.
(FR) Polymeres comprenant des unites recurrentes qui, en presence d'un ion argent ou d'un complexe d'argent, sont capables de se cliver ou qui, en presence d'un agent d'oxydation ou de reduction, forment un produit de reaction capable de se cliver de maniere a liberer du polymere un radical monovalent. Dans un mode de realisation preferentiel, le materiau libere comprend un groupe dans le domaine de la photographie. L'invention se refere aussi a des produits photographiques et a des procedes utilisant des polymeres comprenant des unites recurrentes qui, en presence d'un agent initiant le clivage present dans une distribution selon l'image en tant que resultante du developpement d'une emulsion d'halogenure d'argent, subissent un clivage pour liberer une distribution correspondant a l'image, d'un groupe utile.
