<P>PROBLEM TO BE SOLVED: To provide a curable type mat coat varnish for screen printing giving homogeneous and sufficient mat effect by means of a single varnish. Ž<P>SOLUTION: A curable type mat coat varnish for screen printing includes a crystalline poly-alpha olefin resin which has a structure originated from a 10-35C alpha-olefin, and has a melting point (Tm) of 40-100°C. The melting point is obtained by using a differential scanning calorimeter (DSC) from a melting endothermic curve which is obtained by retaining the polymer at 190°C for 5 minutes under nitrogen atmosphere, subsequently cooling to -10°C at 5°C/min., then keeping at -10°C for 5 minutes, and heating to 190°C at 10°C/min.
