Abstract:
1. A method for forming an image on a transparent member, the method comprising: a) forming a coating layer on a surface of the transparent member; b) attaching a dry film photoresist on the coating layer; c) exposing the dry film photoresist by covering the dry film photoresist with a photo mask having an image pattern and irradiating the photo mask with UV; d) performing a development process for removing other area of the dry film photoresist except for an image area of the dry film photoresist irradiated with UV through the image pattern of the photo mask; e) performing an etching process for removing other area of the coating layer except for the image area of the coating layer facing the image area of the dry film photoresist; and f) performing a strip process for removing the image area of the dry film photoresist, wherein in the step f), after removing the dry film photoresist, a photo transmittance of the image coating layer formed on the transparent member is 50 to 95%, and when a side of the transparent member having the image coating layer is referred to as a back side and an opposite side thereof is referred to as a front side, in the case of irradiating the back side of the transparent member with light, the image coating layer is not seen on the front side of the transparent member and in the case of not irradiating with light, the image coating layer is seen on the front side of the transparent member.
