<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a color lens, and a color lens which has excellent dispersibility of a composition liquid containing a pigment and excellent transparency. <P>SOLUTION: In a method for manufacturing a color lens including a primer process for forming a primer layer 12 on the surface of a lens base material 10 and a surface process for forming a surface layer on the surface of the primer layer 12, the primer process includes a pH adjustment process for adjusting pH by mixing ink containing a pigment having a sulfone group with a basic substance, a composition liquid adjustment process for adjusting a primer composition liquid 121 by mixing the ink whose pH is adjusted with a resin material such as polyester resin or polyurethane resin, and an application process for forming the primer layer 12 by applying the primer composition liquid 121 on a surface 10A of the lens base material 10 by an ink jet method, and the pH of the ink is 2.8 or more and 8.2 or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
