Photocurable ink, patterning method, and package structure

The invention relates to light-cured ink, a patterning method adopting the light-cured ink and a packaging structure. The photocurable ink comprises: 1 part by weight of resin; 1.5 to 3.5 parts by weight of a diluent; and 0.25 to 1.5 parts by weight of a photosensitizer wherein the chemical structure of the resin is: or R1 is a C2-16 alkyl group, phenyl group, tolyl group, benzyl group, or R5 is a C2-10 alkyl group; r2 is or and R3 and R4 are each H, C1-15 alkyl, C2-15 alkenyl, or phenyl, where the photocurable ink has a viscosity at room temperature of from 4 cps to 50 cps, and where the photocurable ink has an acid value of from 0 mg/KOH to 60 mg/KOH. 本发明涉及一种光固化墨水、采用该光固化墨水的图案化方法与封装结构。所述光固化墨水包括：1重量份的树脂；1.5至3.5重量份的稀释剂；以及0.25至1.5重量份的感光剂，其中树脂的化学结构为或R1是C2-16的烷基、苯基、甲苯基、苯甲基、或且R5是C2-10的烷基；R2是或以及R3及R4各自为H、C1-15烷基、C2-15烯基、或苯基，其中光固化墨水的室温粘度是4cps至50cps，以及其中光固化墨水的酸价是0mg/KOH至60mg/KOH。
