The present invention relates to an aqueous alkali-developable photosensitive polyimide precursor resin composition that is appropriate for highly heat-resistant transparent protection layers and insulation layers for liquid crystal display devices. In more detail, the present invention relates to a negative-type photosensitive transparent polyimide precursor resin composition manufactured in two steps. The first step is the manufacture of a transparent linear polyamic acid (A) from (a-1) one or more kinds of tetracarboxylic acid dianhydrides selected from alicyclic tetracarboxylic acid dianhydrides having 3 to 30 carbon atoms; and (a-2) one or more kinds of diamines selected from aliphatic, alicyclic, or non-conjugated aromatic diamines, having 3 to 30 carbon atoms, having one or more ethylenically unsaturated bonds at side chains as essential components; and the second step is the manufacture of reactive transparent polyimide precursors shown in the following Chemical Formula 1 according to the esterification reaction of the above polyamic acid (A) with ethylenically unsaturated compound (B) containing an epoxy group in the same molecule as the main component. The photosensitive transparent polyimide precursor resin compositions according to the present invention have a superior photosensitivity, and thus, may be used for transparent protection layers and insulation layers of liquid crystal display devices having superior heat resistance, chemical resistance, mechanical strength, and electricity insulation.

Disclosed herein is a structurally improved golf glove capable of accelerating a club head as much as possible when swings are made, and maintaining good directivity, by maintaining correct swing form and/or correcting incorrect swing form when practicing or playing golf, and allowing the club head to impact a golf ball exactly perpendicularly, thereby being innovative in increasing the flying distance of the ball. The golf glove used when practicing or playing golf includes a glove body for maintaining and/or correcting golf swing postures, into which a golfer's fingers are inserted, enclosing the golfer's hand, a tightening means formed inside the glove body, providing elasticity, with which the glove body is brought into close contact with the golfer's hand, and a loop means taking the shape of a looped strip, at least one end of which is detachable from the glove body, and the other end of which is fastened to the back of the hand of the glove body by at least one fastening means, wherein the loop means is looped around the rear end of the grip of the golf club. According to the present invention, the club head can be maximally accelerated in downswings, and correct and square impacts are made between the ball and the club head. Thus, good directivity can be maintained, thereby being innovative in increasing the flying distance of the golf ball.
