摘要:
An information recording medium has a recording layer which comprises a composition containing:I) at least one organic polymer selected from the group consisting of:(a) conjugated polymers whose conformations change by thermal energy, for example, polythiophene, and(b) polymers containing as a component a diene monomer and/or an aromatic-ring-containing vinyl monomer, for example, polystyrene; andII) a dye having light-absorbing ability, for example, naphthalocyanine. Despite the recording layer is of the organic type that features non-toxicity and low manufacturing cost as advantages, the recording layer makes it possible to produce a rewritable optical disc which can be recorded by a semiconductor laser (830, 780 nm) employed widely.

摘要:
A phosphor pattern for a field emission display panel (FED) is provided. The phosphor pattern is formed by a process whichh comprises the steps of: (I) forming (A) a photosensitive resin composition layer containing a phosphor on a substrate to which a conductive layer is formed; (II) selectively irradiating active light to (A) the photosensitive resin composition layer containing a phosphor, for forming a pattern; (III) selectively removing (A) the photosensitive resin composition layer to which active light has been selectively irradiated by development, to form the pattern; and (IV) calcining the pattern to remove an unnecessary portion, to form the phosphor pattern. Also provided ar this process for forming the phosphor pattern, a photosensitive element for a FED and a field emission display panel. In forming the layer on the substrate, the photosensitive resin composition layer can be provided as a layer of a photosensitive element, and the element provided on the substrate such that the layer contacts the substrate.
