Description

1307345 IX. Description of the Invention: [Technical Field] The present invention relates to a spherical branched structure containing a polyuv crosslinking reaction group, and more particularly to the use of the compound in an ink jet ink composition. [Previous Technology 4] A variety of inkjet technologies have been applied to fast printing. The more common methods include continuous ink jet printing and drop-on-demand. The former can use the principle of electric power to produce skew, such as bidirectional skew and multidirectional skew, and supply ink according to the way of inkjet when charged and not inked when not charged. The latter principle is usually the following two ways: moving the piezoelectric transformer to generate pressure waves to form ink droplets, commonly known as piezoelectric method, and the other to form ink droplets by heat pulse, commonly known as thermal bubble type. The composition of the ink can be roughly classified into a water-soluble type, an oil-soluble type, a solvent type, a hot-melt type, and a photo-curing type. Since the first two types of mechanisms are quite dependent on the absorption and drying of ink, the latter three are more suitable for use on metals, ceramics, plastics and other materials that do not absorb ink. The present invention is particularly directed to photocurable inkjet inks. The most important and basic patent is U.S. Patent No. 4,303,924 which discloses the use of a plurality of carbonaceous carbon double bonds of low molecular weight molecules as photohardenable components. Other photohardenable inks disclosed in the Republic of China Patent No. 207302, or by the Republic of China Patent No. 207308, which utilizes a monomer, an oligomer, or a resin containing a carbon-carbon double bond as a photohardenable component of a pigment. And apply the pigment to the production of LCD color filters. U.S. Patent No. 4,680,368 discloses a photohardenable ink composition comprising a poly-ammonium phthalate. European Patent No. A0465039 and A0540203 also disclose photohardenable inks containing a plurality of polymerizable monomers. These patents are difficult to avoid problems such as insufficient adhesion, resistance, insufficient heat, and embrittlement caused by insufficient cross-linking. In addition to ό 0424-A21283TWF(N2); P02940035TW; hsuhuche 1307345, the flowability of the ruthenium will cause problems in the stability of the pigment dispersion. However, if the chain photohardenable component is elongated to increase its stability, the viscosity of the ink in the inkjet crucible is raised 9' to solve this problem, and it is necessary to introduce a plurality of photohardenable monomers for fine adjustment. This will cause trouble in the subsequent (four) good and quality control, and then increase the cost. Therefore, how to further design a photohardenable molecule that solves the above problems, and then apply it to inkjet inks. Dendrimers have been widely used in the pharmaceutical, synthetic, and super-knife subspecies in recent years due to their large number of modifiable branches. The use of dendrimers in photohardenable inks includes the polyacetamides disclosed in US 2005/0147834 A1, but as with those skilled in the art, the ends of the branches of the patent are also aminated. And the photohardening reaction cannot be performed. The stick disclosed in US 6,221,933 B1 has a terminal amine group to improve the moisture resistance of the ink on the surface of the glass, and the sprayed film water can be washed with alkali water to recover the glass. Even though the dendrimer disclosed in US 6,300,388 B1 has a counter-double bond of a disc which can undergo photohardening reaction, the branch is still an aminate, but a double bond placed inside the molecule rather than at the end will cause photohardening reaction. The steric barrier and reduce the rate and extent of ink curing. In addition, many people suspend the dye chromophores at the ends of the dendrites, one of which is 2003/0096885A1. Although it can improve the ink-jet properties and enhance the light, water and stain resistance, it still lacks the US 6,300,388 B1. Photohardening terminal functional group. The core species of dendrites is a basic but important choice. Generally, planar molecules such as triazine or benzene are used as the central molecule, but the aroma and planarity of the above two are not easily caused to crosslink in 3D, and the physical properties such as hardness and light resistance are lowered. Therefore, many improvements have been made in this regard, one of which is U.S. Patent Publication No. US 2004/0163570 A1 'A symmetrical symmetry of a rock cage that is circumscribed with a plurality of branches to form a multi-bond ball (non-dendritic body) ) 'The end is; 5 carbon double bonds for photohardening. Although the core of the patent can avoid the problem of steric obstacles, but the 0424-A21283TWF{N2); P02940035TW; hsuhuche 7 1307345 -, too large stone oxygen cage and unusual chemical characteristics, will be further extended and improved It is more difficult to use organic molecules as the core. _ [Summary of the Invention] In view of this, the present invention particularly provides a spherical branch = structural compound containing a multi-uv crosslinking reaction group, comprising - a core, the structure of which is a hetero-cyanate group; a plurality of knives A dendritic substituent having a backbone containing a plurality of polar functional groups and having a terminal end with a uv cross-linking reactive group.

There are two main ways in which the branches can be synthesized: divergent from the inside to the outside and convergent from the outside to the inside. If the "generation" between the core and the terminal functional groups is more, the convergence is better; if the generation is less, the simple divergence is dominant; Thereafter, it is bonded to a terminal functional group of the astringent synthesis to form a target molecule. Since the present invention has fewer generations, the divergence type is the main synthesis strategy, but it can also be synthesized in a convergent manner or both. For example, starting materials containing core isocyanurate groups include trichloroisocyanuric acid, tris(2,3 epoxypropyl)-isocyan cyanide Tris(2,3-epoxypropyl)isocyanurate, triacrylic isocyanurate (triallyl-l,3,5-triazine-2,4,6(lH,3H,5H)-trione), preferably starting The material is tris(2,3 epoxypropyl)-isocyanate.

Finally, other unreacted polar functional groups such as a slow acid group on the aryl group are reacted with a compound having a UV crosslinking reaction group at one end to obtain a spherical branched structure compound having a multi-UV crosslinking reaction group. The polar functional groups do not react with the UV crosslinking reaction group, but react with other functional groups of the compound, such as an epoxy group (opening reaction) and a halogen group (substitution reaction). If the aromatic group having a polar functional group has a structure of & dec-Cm-X) n, the compound having a uv cross-linking reactive group at the terminal must have a nucleophilic functional group such as a hydroxyl group or an amine group to carry out a substitution reaction instead of a ring.
