Abstract

Disclosed herein is a printing resist sequentially transferred to a printing plate and a substrate after being applied to a printing roll. The printing resist comprises at least one polymer main chain bound to a tackiness-inducing vinyl group. The surface of the printing resist has tackiness without complete dryness, thus enabling a correct transfer of the printing resist to the printing plate and substrate.

Claims (19)

1. A printing resist sequentially transferred to a printing plate and a substrate after applied to a printing roll, wherein the printing resist comprises at least one polymer main chain bound to a tackiness-inducing vinyl group, and wherein the polymer main chain is cresol;

wherein the cresol is meta-cresol,

wherein a printing resist comprising the meta-cresol as the polymer main chain is represented by formula 1 below:

wherein 1≦k1≦10 and 0≦m1≦10.

2. A printing resist sequentially transferred to a printing plate and a substrate after applied to a printing roll, wherein the printing resist comprises at least one polymer main chain bound to a tackiness-inducing vinyl group, and wherein the polymer main chain is cresol;

wherein the cresol is para-cresol,

wherein a printing resist comprising the para-cresol as the polymer main chain is represented by formula 2 below:

wherein 1≦k2≦10 and 0≦m2≦10.

3. A printing resist sequentially transferred to a printing plate and a substrate after applied to a printing roll, wherein the printing resist comprises at least one polymer main chain bound to a tackiness-inducing vinyl group, and wherein the polymer main chain is cresol;

wherein the cresol is meta-cresol and para-cresol,

wherein a printing resist comprising the meta-cresol and the para-cresol as the polymer main chains is represented by formulae 3 to 5 below:

wherein 1≦k3≦10 and 1≦m3≦10;

wherein 1≦k4≦10 and 1≦m4≦10 and

wherein 1≦k5≦10 and 1≦m5≦10.

4. The printing resist according to claim 1 , further comprising a volatile solvent.

5. The printing resist according to claim 4 , wherein the volatile solvent is methanol, ethanol, or iso-prophyl alcohol.

6. The printing resist according to claim 1 , further comprising a surfactant.

7. The printing resist according to claim 6 , wherein the surfactant is a semi-fluorinated surfactant.

8. The printing resist according to claim 7 , wherein the semi-fluorinated surfactant is CF 3 (CF 2 ) 4 (CH 2 CH 2 O) 10 , or CF 3 (CF 2 ) 5 (CH 2 CH 2 O) 14 .
