DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor treatment agent which exhibits gloss and darkening to a synthetic resin floor material such as a cushion floor or a wooden floor such as a flooring and has a protective property.

[0002]

2. Description of the Related Art Wood flooring and synthetic resin flooring are widely used as flooring materials for houses. For protection polishing of these flooring materials, resin polymers based on styrene-acrylic copolymer latex or the like are used. However, these floor polishes had to be cleaned prior to use at the place of use. In view of this, the present applicant has previously disclosed in Japanese Patent Application Laid-Open No. Hei 6-33016, a surfactant and a glycol-based solvent to provide a detergency to a floor polish, to remove dirt and perform polish by a single wiping cleaning. We have developed and proposed a polished floor cleaner with the following characteristics. Japanese Patent Application Laid-Open No. 9-188553 discloses that a beautiful and glossy surface can be maintained for a long time by blending a water-insoluble polymer emulsion and a polyolefin wax composed of polyethylene and polypropylene together with a hydrophilic solvent in a specific ratio, and A floor-washing polish that reduces slippage during walking is described. However, the conventional technology is insufficient in detergency, and further improvement has been required. An object of the present invention is to provide a floor treating agent having detergency and gloss by treatment, and further having scratch resistance.
