整することが要求される。The ability to form high-precision, high-density patterns by printing is extremely useful industrially. In order to print high-precision patterns without printing defects such as bleeding, blurring, or pinholes, the ink must have thixotropic properties (thixotropy).
It is necessary to adjust the flow characteristics according to the printing conditions and the printing target.

するのが精−杯である。In the case of color printing, the use of conventional ink compositions results in poor image sharpness and sharpness due to misalignment of halftone dot patterns, bleeding, poor linearity, and the like. Furthermore, in the manufacture of printed circuit boards using the resist ink composition cited above, the accuracy and resolution of printed patterns are insufficient, and industrially, it is difficult to form a pattern of 250 μm. It is.
インキ組成物の印刷特性は、使用する樹脂の性能の他に

For curing these resin components, heat drying, heat curing, UV curing, etc. can be employed, and a curing agent may be added if necessary. Examples of dilutable solvents for heat-drying inks include ethyl cellosolve, butyl cellosolve acetate, methyl carpitol, butyl carpitol, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, n-hexane, etc.
In addition, thermosetting and UV-curing inks include diethylene glycol di(meth)acrylate, tripropylene glycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, and pentaerythritol tri(meth)acrylate.
(meth)acrylate monomers such as (meth)acrylate, epoxy monomers such as t-butylphenyl glycidyl ether, tripropylene glycol diglycidyl ether, neopentyl glycol diglycidyl ether, and vinyl ether monomers such as triethylene glycol divinyl ether are used. Ru.

性が低下するので好ましくない。The amount of liquid polybutadiene resin and/or hydrogenated liquid polybutadiene resin added to the ink composition is 0.5 to 30 parts by weight, preferably 1 to 30 parts by weight, based on 100 parts by weight of the ink.
It is 15 parts by weight. If the amount of liquid polybutadiene resin and/or hydrogenated liquid polybutadiene resin blended into the ink composition is too small, the desired thixotropic imparting effect will not be sufficient, and if it is too large, printability will decrease. So I don't like it.

あるにかかわらず、あたかも無機充填剤を配合した場合
と同様に挙動し、組成物にチクソトロピーを付与する。In the present invention, the liquid polybutadiene resin and the hydrogenated liquid polybutadiene resin are not compatible with the resin component usually used as a vehicle for ink compositions. Regardless of whether it is present or not, it behaves as if an inorganic filler were added and imparts thixotropy to the composition.

ることもできる。Furthermore, on the surface of the printed ink, it acts as an antifoaming agent and a leveling agent, forming a smooth surface and improving the linearity of the printing line. Therefore, when preparing the ink composition, it is also possible to omit the addition of a leveling agent and an antifoaming agent.
本発明においては、これらが相乗的に作用し、チクソト

となる。In the present invention, these act synergistically to improve resolution by increasing thixotropy, and
The printing lines are straight and sharp patterns are formed. Furthermore, since bleeding and deterioration of adhesion that occur in the case of a low-viscosity composition are prevented, high-precision printing becomes possible.
