A near infrared ray activation type positive resist composition comprising

Near infrared ray activation type positive resin composition

Method of diminishing odor emission

The object of the present invention is to provide resin compositions conferring cured materials (a coating or the like) with excellent appearance, excellent mechanical properties, or the like. The present invention provides resin compositions containing a vinyl copolymer with an epoxy group and a branched glutaric acid.

Resin composition

Diglycidyl ethers

The present invention provides a process for producing polyhydroxycarboxylic acids which have a weight-average molecular weight of 50,000 or above and which are excellent as biodegradable plastics by polycondensing hydroxycarboxylic acids or oligomers thereof in the presence of an inorganic solid acid catalyst in combination with an alkali metal or an alkaline earth metal.

Process for producing polyhydroxycarboxlic acid

Disclosed is a process for producing a composition for ruminants, which is characterized in that a nucleus containing a physiologically active substance is coated with a coating material prepared by suspending in water (i) an emulsion comprising water and at least one hydrophobic substance hardly soluble in water and (ii) a slurry containing at least one polymer soluble in water of pH 5.0 or below and insoluble in water of pH over 5.0 In the process, an aqueous suspension is used for coating instead of a meterial dissolved in an organic solvent.

Process for producing compositions for ruminants

By coating a solid fertilizer with a coating material comprising an aqueous emulsion of resin as the main component to form a resin film having a glass transition temperature of 60.degree. C. or higher; or by coating a solid fertilizer with a coating material comprising an aqueous emulsion of a thermoplastic resin and a melamine resin, and heating the coated fertilizer at 70.degree. C. or higher; a gradually-effective, coated fertilizer having a distinguished gradual releasability and strong resistance to caking, which have been so far regarded as difficult to be obtained in an aqueous emulsion system, can be prepared.
