Problems solved by technology

However, in the inkjet recording method, low-viscosity ink is used from the viewpoint of dischargeability, and oxygen easily diffuses / enters the ink from the atmosphere.
In addition, since the ink is printed in small droplets, the surface area becomes larger and it is easily exposed to oxygen
In addition, curing inhibition by oxygen is significant, and a large amount of unreacted monomers that cause leakage or cause odors remain a problem.
In addition, there is also a problem that the substrate surface needs to be processed in order to improve the ink adhesion due to low substrate adhesion.

Embodiment 1

[0217] Each component was mixed as in the formulation described in Table 1 (units are parts by weight) to obtain an ink. As a result of measuring the viscosity of the obtained ink at 25°C and a shear rate of 100 (1 / s) using an E-type viscometer (trade name "VISCOMETER TV-25", manufactured by Toki Sangyo Co., Ltd.), it was 12 mPa·s .

Embodiment 2～19、 comparative example 1～2

[0219] Inks were obtained in the same manner as in Example 1, except that the formulations were changed as described in the following table (units are parts by weight).

[0220] (Curability evaluation in high humidity environment)

[0221] Using a wire-wound bar coater (#4), the inks obtained in Examples and Comparative Examples were applied to a glass plate (trade name "S9112", manufactured by Matsunami Glass Industry Co., Ltd.) or an aluminum plate (trade name "A1050P", AS ONE Co., Ltd.) (coating film thickness: 5 μm), under the conditions of 24 to 25 ° C, air atmosphere, and humidity of 50 to 80%, using an LED irradiator (trade name "UV-LED PROCESSOR LSS-05", CCR Manufactured by the company) as a light source [make the amount of irradiation (exposure) 1J / cm 2 , Repeated irradiation until it becomes non-sticky] 365nm light (illuminance: 1.5W / cm 2 ), curability was evaluated according to the number of times of irradiation.

Abstract

Provided is a monomer mixture which is rapidly cured even in high humidity environments and is useful as a raw material for a curable composition capable of forming a cured product having excellent adhesion to paper and plastic as well as metal and glass. This monomer mixture is composed of two or more cationically polymerizable monomers, and contains, as the cationically polymerizable monomers, acompound (A) having a vinyl ether group and a hydroxy group, a compound (B) having an oxetanyl group and a hydroxy group, and a compound (C) represented by formula (c), wherein the total content of compound (A), compound (B), and compound (C) is at least 50 wt% with respect to the total amount of the monomer mixture, and the content [A] of compound (A) and the content [B] of compound (B) satisfyequation (1). (1) A / (A+B)>=0.3.

Description

technical field [0001] The present invention relates to a monomer mixture and a curable composition containing the monomer mixture. This application claims priority based on Japanese Patent Application No. 2018-018095 filed in Japan on February 5, 2018, and the contents thereof are incorporated herein. Background technique [0002] The inkjet recording method, in which printing is performed by flying ink droplets to a recording medium to form recording dots, does not require a master plate, so it is suitable for printing a large number of items in small quantities. As inkjet inks used in this inkjet recording method, cation-curable inks and radical-curable inks are known. [0003] Such radical curable inks are increasingly used for reasons such as rapid curing and rich types of monomers. However, in the inkjet recording method, low-viscosity inks are used from the viewpoint of discharge properties, and oxygen tends to diffuse and enter the ink from the atmosphere. In addi...
