Provided are a curable maleimide resin composition and others, in which the curable maleimide resin composition is one that does not employ an aprotic polar solvent such as NMP, can be cured at a temperature lower than 250? ? C. which is a temperature at which a normal polyimide cures, and can particularly be turned into a cured product having a superior adhesiveness to copper. The curable maleimide resin composition contains: (A) a maleimide compound that has a bisphenol structure and a number average molecular weight of 5,000 to 50,000; (B) a reaction initiator; and (C) a diaminotriazine ring-containing imidazole.

To obtain a hydrophilic macromonomer mixture which is a highly polymerized hydrophilic macromonomer, has few components not bonded to the polymer chain after polymerization, and is less likely to leaching. Provided is a macromonomer mixture containing macromonomer A being a macromonomer having a group obtained by further introducing a polymerizable group into a reactive group derived from a polymerization initiator at an end thereof; and macromonomer B being a macromonomer having a group obtained by further introducing a polymerizable group into a reactive group derived from a chain transfer agent at an end thereof.

A photosensitive resin composition and a manufacturing method thereof, a black matrix, a pixel layer, a protective film, a color filter, and a liquid crystal display apparatus are provided. The photosensitive resin composition includes an alkali-soluble resin (A), a compound (B) containing an ethylenically-unsaturated group, a photoinitiator (C), and a solvent (D), wherein the alkali-soluble resin (A) contains a first alkali-soluble resin (A-1) having all of a fluorene group, a polymerizable unsaturated group, and a carbamate group. The photosensitive resin composition contains a specific alkali-soluble resin (A-1), so that a pattern formed by the photosensitive resin composition has no development residue and good sputtering resistance.

The present invention relates to non-halogenated and non-metal polymerizable flame retardants, their preparation, compositions containing the same and uses thereof. These flame retardants may be polymerized with other ethylenically unsaturated compounds and chemically bound to the resin matrix thus limiting their migration out of the finished product. The flame retardants of the invention are also more environmentally friendly than conventional halogen-based or metal-based flame retardants.
