Background technology
In the past, various resin combinations had been used in coating, sticker.Being matched with the resin of the resin combination can enumerate Such as natural rubber, synthetic rubber, carbamate resins, polyester resin, styrene resin and acrylic resin and it Mixture, wherein from cost, durability, physical property etc. consider, be widely used for styrene resin, acrylic acid series tree Fat.
On the other hand, it is widely used for emulsion resin for the purpose of environmental protection and cost reduction.By the emulsion-type In the case that resin is used in the purposes of coating, sticker (hereinafter referred to as masking liquid), the envelope of film, adhering agent layer is formed, but If not suitably controlling the viscosity of masking liquid in the envelope is formed, it is difficult to obtain smooth and flawless envelope.
For this respect, contain the lotion of polymer using water as decentralized medium, exist as particle.Therefore, it does Even if dry film is at first sight transparent and uniformly as it can be seen that but being easy to generation gap, be not easy shape between microscopic scale, particle and particle At the envelope of flawless densification.
Therefore disclose in patent document 1 obtained by using specific reactive emulsifier and agglutinant it is high non-volatile The method of the lotion containing polymer of ingredient.
In addition the lotion containing polymer that polymer is prepared by 2 stages is disclosed in patent document 2.
In addition the high nonvolatile component Patent Document 3 discloses the amount by adjusting polymerization initiator and emulsifier The lotion containing polymer.
However, the amount of polymerization initiator, emulsifier is considerably less.Therefore, according to initiator, the measuring accuracy of emulsifier and it is outer Sight state is easy to change, it is difficult to steady production.In addition, the mechanical stability of lotion is also insufficient.
The different latex particle of grain size (エ マ Le シ ョ Application particle) is mixed and improved in addition, being disclosed in patent document 4 Make film property and the lotion containing polymer of adhesive performance.
