A photosensitive material and methods of making a pattern on a substrate are disclosed. The photosensitive material includes a polymer that turns soluble to a developer solution after a chemically amplified reaction, and at least one chemical complex having a single diffusion length. The material includes at least one photo-acid generator (PAG) linked to at least one photo decomposable base (PDB) or quencher.

A compound, an acrylic polymer formed by a copolymerization reaction of the compound with an ethylenic unsaturated monomer, photosensitive resin composition including the compound being represented by Chemical Formula 1 and a color filter:

##STR00001##

The invention relates to a recording element which is suitable for producing high-resolution flexographic printing plates by means of digital information transmission and which can be imaged by means of actinic laser radiation, containing or consisting of the following layers: (A) a carrier film, (B) a photopolymerizable layer/relief layer which can be crosslinked by means of actinic radiation, (C) optionally an intermediate layer which is transparent to actinic radiation as a separating element, and (D) a template layer which is capable of recording and comprises a monomer diazonium compound or (Da) an imaged template layer. The invention likewise relates to a semi-finished product, to a method for producing the recording element, and to a method for producing flexographic printing plates.

A photosensitive resin composition which gives a cured film having high light shielding properties and enables stable curing by baking at low temperature, a cured film obtained by curing the composition, a display device provided with the cured film, and a pattern forming method using the composition. A light shielding film-forming process which does not impart thermal damage to a light-emitting element with respect to a substrate provided with a light-emitting element. In a photosensitive resin composition including a binder resin, a photopolymerizable compound, a photopolymerization initiator, a coloring agent, and a thermosetting compound, a carbon black and/or an inorganic black pigment, and an organic pigment are used in combination as the coloring agent, and a photosensitive resin composition in which T2/T1 is 0.80 or more is used.
