Abstract
Official abstract text for this publication.
A printed board, a screen-printing ink, and a screen-printing method are provided. The printed board comprises a printed pattern and/or printed line which comprises a polymer binder and a fluorine-based surfactant, has excellent thickness uniformity and straightness, has no edge top defect, and is not damaged even when formed on a repeatedly folded substrate.
First claim
Opening claim text (preview).
The invention claimed is: 1. A printed board comprising: a substrate; and a printed pattern formed on the substrate, wherein the printed pattern comprises one or more printed lines, wherein the printed line comprises a polymer binder, a colorant, and a fluorine-based surfactant, wherein the colorant is a black pigment or dye, or mixtures thereof, wherein the colorant is comprised in a ratio of 25 to 85 parts by weight relative to 100 parts by weight of the polymer binder, wherein in the printed line, the polymer binder is comprised 50 to 70 parts by weight relative to 100 parts by weight of the printed line, and wherein the printed line has thickness uniformity, a difference between the maximum thickness and the minimum thickness, of 0.6 μm or less and an edge top deviation, an absolute value of a difference between an average thickness of the printed line and thickness of an edge portion of the printed line having the average thickness, of 0.55 μm or less. 2. The printed board according to claim 1 , wherein the printed line has a thickness in a range of 0.5 μm to 10 μm. 3. The printed board according to claim 1 , wherein the printed line has straightness of 50 μm or less, wherein the straightness is obtained by analyzing an image measured with an optical microscope. 4. The printed board according to claim 1 , wherein the printed pattern is a bezel pattern. 5. The printed board according to claim 1 , wherein in the printed line, the fluorine-based surfactant is comprised in an amount of 0.25 to 2.5 parts by weight relative to 100 parts by weight of the polymer binder.
