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).
