Abstract:
The present invention relates to a positive-working photosensitive resin precursor composition which is characterized in that it contains (a) polymer in which the chief component comprises structural units of the kind where the bonding between structural units is represented by general formula (1) and (b) photoacid generator, and it can form a pattern by light irradiation and subsequent developing, and the total carboxyl groups contained in said polymer is from 0.02 to 2.0 mmol/g, and it provides a photosensitive resin composition of high sensitivity which can be developed by alkali. (R is an organic group of valency from 3 to 8 having at least 2 carbon atoms, R is an organic group of valency from 2 to 6 having at least 2 carbon atoms, R is hydrogen or an organic group with from 1 to 20 carbons. n is an integer of value from 3 to 100,000, m is 1 or 2, p and q are integers of value from 0 to 4 and p + q > 0.)

Abstract:
The present invention provides an aggregate of carbon nanotubes which has an acid adsorption amount equal to or greater than 0. 6 mass% and equal to or less than 12 mass%, which is obtained by subjecting a starting material composition containing carbon nanotubes to a two-stage wet oxidation treatment. The present invention provides an aggregate of carbon nanotubes capable of exhibiting excellent electrical conductivity when used to configure a transparent conductive film, and a production method therefor.
Abstract:
A positive photosensitive resin precursor composition characterized by comprising (a) a polymer consisting mainly of structural units bonded to each other in the manner shown by general formula (1) and (b) a photo-acid generator, being capable of forming a pattern through light irradiation and subsequent development, and having a total carboxyl group content of 0.02 to 2.0 mmol per g of the polymer. It provides a photosensitive resin composition which is capable of alkali development and is highly sensitive. (R represents a tri- to octavalent C2+ organic group; R represents a di- to hexavalent C2+ organic group; R represents hydrogen or a C1-20 organic group; n is an integer of 3 to 100,000; m is 1 or 2; and p and q each is an integer of 0 to 4, provided that p+q>0).
