The disclosure relates to a coating composition for forming a coating film on a granular fertilizer in order to delay the release of plant nutrient elements therefrom. The coating composition includes an oil-modified alkyd resin and an unsaturated oil containing a conjugated double bond. The granular fertilizer can be coated with the coating composition without using an organic solvent.
摘要:
A shaped or unshaped article of a non-ferrous metal sheet preferably aluminum having an organic, surface coating film containing conductive and/or semiconductive fine particles, preferably molybdenum dissulfide is integrally bonded with a shaped or unshaped article of a steel sheet having or not having an organic, surface coating film; and this integrated body is subjected simultaneously to electrodeposition coating.The non-ferrous metal sheet having an organic, surface coating film containing conductive and/or semiconductive, fine particles shows excellent electrodeposition coating characteristics which can be easily regulated. Hence, integral coating after bounding with a steel sheet gives the same degree of film thickness and surface smoothness on both of the non-ferrous metal and steel sheets. This method is particularly suitable for the coating of automobile bodies integrally composed of non-ferrous metal and steel sheets ensuring energy- and labor-saving and giving final products of uniform finish.

The present invention is for a method of forming a coating film used for filling the space between the color stripes for a color filter which is used for colorization of a liquid crystal display. In particular, the light-shielding electrodeposition coating is first formed in a transparent electric conductive circuit pattern so as to suppress the reaction of a photo-setting material against light which is to be applied to the electrodeposition coating.

A color filter having discrete color layers arrayed on a substrate and light screening coating films interlaced between the color layers and if desired seal part having no coating film thereon, with high precision is industrially advantageously manufactured by (a) forming a transparent electroconductive layer on a transparent substrate, (b) coating the transparent electroconductive layer with a positive photoresist composition to form a photoresist layer, (c) exposing the photoresist layer to light through a photomask and developing the light-exposed photoresist layer to form a circuit-form photoresist layer, (d) etching and eliminating the transparent electroconductive layer bared in the gaps between the circuit-form photoresist layer to obtain a substrate having thereon a circuit-form laminate, (e) exposing the laminate to light through a photomask and developing the light-exposed laminate to bare the transparent electroconductive layer discretely, (f) carrying out electrodeposition using a thermosetting or photosensitive resin material-containing electro-deposition bath to form colored layers on the discretely bared transparent electroconductive layers, (g) eliminating the photoresist layer remaining after the development of step (e) to obtain a substrate having discrete color layers, the gaps being bared substrate surface and bared transparent electroconductive layer, (h) coating the substrate with a light screening material-containing photosensitive resin composition to form a light screening resin layer, and (i) exposing the light screening resin layer to light from the back side and developing the substrate to eliminate the unexposed part of the light screening resin layer. The color filter is well prevented from leakage of light and clear in coloration and superior in optical properties. A liquid crystal display of high image quality is manufactured by the use of this color filter.

Coating composition containing a resin and fine particles of an electrically semiconductive substance, whereby a coating film to be formed therefrom on a work article surface exhibits a varistor property represented by the following equation (1):I=(V/V.sub.1).sup.n (1)wherein I is a current density (mA/cm.sup.2); V.sub.1 is a voltage at which a current of 1 mA begins to flow when a voltage applied to the coating film is increased; V is an applied voltage; and n is an exponent showing the non-linearity between I and V and is 1.5 or more. Coating films formed from such coating composition exhibit excellent film forming and corrosion-resistant properties.
