As can be seen from Table 1, embodiment 1～6 has preferable anti-fog performance.Initial water contact is below 10 °, and 48 is little
Time soak after water contact angle be below 35 °, anti-fog performance is excellent.Comparative example 1 compared with Example 3, owing to adding sense
The degree hydrophobicity light-cured resin less than 6, although initial stage water contact angle is within 10 degree, but owing to final coating network will not
Close, when causing its Long contact time steam and water soaking, hydrophilic segment network departs from from substrate surface, and makes hydrophilic drop
Low, so anti-fog performance is poor, protracted hydrophilicity is poor.Comparative example 2 compared with Example 3, have employed nonionic photocuring parent
Aqueous monomer, owing to its hydrophilic is less than ionic comonomer, therefore its initial water contact is higher, does not possess anti-fog performance.Contrast
Compared with Example 2, the diisocyanate divided because of employing when hydrophilic resin synthesizes is aromatic series two isocyanide that rigidity is stronger to example 3
Acid esters, the hydrophilic of gained resin is the most very poor, is therefore made into coating photocuring gained coating initial water contact the highest, root
This is the most anti-fog properties.Comparative example 4 is compared with comparative example 2, owing to using than HMDI rigidity weak a lot of aliphatic HDI, although just
Beginning water contact angle is relatively low, but owing to the hydrophilic of resin used is very good, also causes final coating due to water-swellable and make hydrophilic portion
Subnetwork departs from from substrate surface, and in final coating, hydrophobic part is in the great majority, and makes hydrophilic be substantially reduced.And comparative example 5
In, the most do not possess anti-fog performance, because the molecular weight of raw material Polyethylene Glycol is relatively low, therefore gained resin hydrophilic is poor.Right
In ratio 6, owing to the molecular weight of raw material Polyethylene Glycol is higher, itself being i.e. water miscible, therefore the final resin of gained is hydrophilic
Property preferable, initial water contact is relatively low, so having a little anti-fog properties.But after its 48 hours soak, hydrophilic is greatly reduced.This
The hydrophilic being because resin used is very good, cause final coating due to water-swellable and make hydrophilic segment network from substrate surface take off
From, cause hydrophobic part in coating to be in the great majority, and make hydrophilic be substantially reduced.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various deformation or amendment within the scope of the claims, this not shadow
Ring the flesh and blood of the present invention.
