Methods and high visible-light reflective reactive resinous coatings that increase visible light inside a grow house and enhance plant growth therein. A pre-dispersion of a resin, zinc oxide, one or more fillers, and retroreflective microspheres, is mixed with a one-part or two-part reactive coating system to provide a high-reflectance reactive resin coating composition. At least one or more layers of the high-reflectance reactive resin coating composition is coated onto a substrate inside the grow house and allowed to cure. The cured high-reflectance reactive resin layer has a light reflectance increase up to 60% in lumens increasing an amount of visible light inside the grow house to enhance plant growth.

The present inventive concept relates to a copper based conductive paste and its preparation method. The copper based conductive paste comprises a copolymer-copper composite comprising an imidazole-silane copolymer with partially cross-linked structure and a copper powder, a solvent, a binder and an additive. The imidazole-silane copolymer with partially cross-linked structure is introduced into the copper powder whose surface is treated by a hydrochloric acid aqueous solution and a phosphoric acid aqueous solution. The imidazole-silane copolymer is polymerized by using an imidazole monomer represented by following formula 1, a silane monomer represented by following formula 2 and a cross-linking agent. ##STR00001## In Formula 1, X represents a hydrogen atom (H) or a methyl group (—CH.sub.3), and R.sub.1 represents a vinyl group or an allyl group. ##STR00002## In Formula 2, Y represents a methoxy group, a 2-methoxy ethoxy group or an acetoxy group, and R.sub.2 represents a vinyl group.
