[0109] Synthesis of iodonium salt D13:

[0110] Add 23g sodium borate tetrahydrate, 40g acetic acid, 60g acetic anhydride to a 500ml four-necked flask with temperature-controlled heating, mechanical stirring, condensation reflux and nitrogen protection device, stir at 30 ° C for 1.5 hours, then add 58.2g 3,5 -Dimethyl-4-tert-butyl-p-iodobenzene, stirred at 40°C for 1.5 hours, then cooled to 0°C, and then added 43.4g of N-(ethyl acrylate)-2,6-dimethyl-benzoic acid , the temperature is controlled below 5 ℃, the mixture of 30 ml of concentrated sulfuric acid and 30 ml of acetic acid is added dropwise, the temperature is raised to 15 ℃ and stirred for 24 hours, the reaction solution is poured into ice water and stirred for 0.5 hours, extracted 3 times with petroleum ether, 1000ml of ammonium chloride aqueous solution with a mass fraction of 20% was slowly added dropwise, the solid was precipitated, filtered, washed with deionized water, and dried in vacuo. Then the obtained solid ...

Embodiment 1

[0131]Preparation of plate base: A1050 rolled aluminum plate with a purity of 99.5% and a thickness of 0.3 mm was etched in a sodium hydroxide aqueous solution with a mass fraction of 5% at 70 ° C for 20 seconds, rinsed with running water, and immediately used with a mass fraction of 1%. nitric acid aqueous solution. Then in 1% hydrochloric acid aqueous solution, sine wave alternating current at 40°C at 50A / dm 2 The current density was electrolytic roughening for 16 seconds, followed by neutralization with 5% sodium hydroxide aqueous solution by mass fraction for 10 seconds at 40 °C, and washing with water. Finally, at 30 ° C, with a mass fraction of 20% sulfuric acid aqueous solution, at 15A / dm 2 current density, anodized for 20 seconds, and washed with water. At 80°C, the pores were sealed with a 5% sodium silicate aqueous solution for 18 seconds, washed with water, and dried. The plate base thus obtained had an average centerline thickness of 0.5 μm and an oxide film weig...

Abstract

The invention provides an iodonium salt initiator, a treatment-free thermo-sensitive plate precursor containing the iodonium salt initiator, a treatment-free thermo-sensitive plate and application of the iodonium salt initiator, at least one of two para-positions of two benzene rings of the iodonium salt initiator is alkylene which contains carbon or nitrogen or oxygen atoms and contains double bonds at the tail end, and the alkylene can increase steric hindrance of iodonium salt; meanwhile, the alkylene can participate in the cross-linking reaction of an imaging layer during laser imaging, so that the damage of small molecules generated by the decomposition of iodonium salt to the imaging layer is reduced. The iodonium salt initiator can effectively solve the problems of surface migration and residue of an onium salt initiator in an imaging layer in the prior art, and can improve the performance of a treatment-free thermosensitive plate, especially a treatment-free thermosensitive plate containing discrete particles.

Description

technical field [0001] The invention belongs to the technical field of lithography, and in particular relates to an iodonium salt initiator, a treatment-free heat-sensitive plate precursor and a treatment-free heat-sensitive plate and application thereof. Background technique [0002] Computer-to-plate technology (CTP technology) is widely used in modern printing. Common CTP plates are divided into photosensitive CTP plates and thermal CTP plates. [0003] Thermal CTP plate (referred to as thermal plate) is an offset printing plate that uses infrared lasers for imaging. Thermal plates are widely used due to their bright room operation and high image quality. [0004] The printing industry is a highly polluting industry that is not friendly to the environment, especially the waste developer produced in the printing process causes great harm to the environment. Therefore, the printing industry all over the world is advocating the implementation of green printing technology. ...
