Abstract
Generally, the invention relates to an ozone-friendly correction fluid that has improved writeover characteristics. The ozone-friendly correction fluids thus have a key benefit (good writeover characteristic) associated with halogenated hydrocarbon solvent, but also have the environmental benefits associated with ozone-friendly solvent. Specifically, the present invention relates to an ozone-friends correction fluid comprising a non-halogenated hydrocarbon solvent, a polymeric phase and an opacifying phase, wherein the ratio of opacifying phase to polymeric phase is from about 2.2 to about 3.8 preferably from about 2.4 to about 3.6 (based on weight).
Description
The present invention relates to opaquing fluid.
Opaquing fluid is used to revise the mark of hand-written, printing on paper, duplicating, Laser Printing.Usually, opaquing fluid is coated with the paper surface that is used for wrong mark in the mode of liquid state.Liquid forms a skim subsequently, and this film on the error flag on the covering surfaces, has been received correction effect effectively.On this film, carry out correct mark and be commonly called " rewriting ".
Opaquing fluid generally includes some standard ingredients, comprises opaque colorant (normally titanium dioxide), film-forming polymer material and solvent.
Opaque colorant is dispersed in the fluid, and basic white is provided, and available other colorant is adjusted this tone makes opaquing fluid approach to be coated with the color of the paper on it.Opaque colorant is used to hide opaquing fluid and is coated with wrong mark on it.
The film-forming polymer material is also referred to as binding agent, and it sticks at colorant on the paper, and forms toughness and successive tectum after solvent evaporates.
Solvent is used as the carrier of other composition in fluid.Halohydrocarbon was used as the solvent in the correction fluid composite in the past.Because the rate of volatilization of halohydrocarbon is fast and volatilization makes it that special advantage is arranged fully.In addition, they can not interact with stamped mark and produce undesirable bleeding.And they can dissolve these film-forming polymer materials effectively, the durable and flexible film of this material production, and can not cause curl and distortion.Although these significant advantages are arranged, when they are used as the solvent of opaquing fluid, received concern, main because they have disadvantageous effect (stratospheric ozone loss) to environment.Therefore, need provide a kind of " harmless " opaquing fluid by the use of eliminating halohydrocarbon to ozone.The harmless opaquing fluid of ozone is meant a kind of like this opaquing fluid, it or do not contain the material that can move in the stratosphere, even perhaps contain these materials, this material also can not cause the reduction of ozone concn.
Having carried out research replaces halohydrocarbon to make solvent with non-halohydrocarbon.The system of describing among aqueous based systems such as the USPNo.5332599 does not have effect to various ink formulations.In addition, non-halogenated hydrocarbon solvent, that for example describes among the US P No.5199976 and 5306755 can cover all kinds printing ink, but overwrite performance is very poor.
The purpose of this invention is to provide a kind of non-halogenated hydrocarbon solvent system with improved overwrite performance.
The present invention relates generally to a kind of have improved overwrite performance to the harmless opaquing fluid of ozone.Therefore, this has and the key advantage (good overwrite performance) that interrelates based on halogenated hydrocarbon solvent the harmless opaquing fluid of ozone, and the advantage to environment that has and get in touch based on the harmless solvent phase of ozone.
Specifically, the present invention relates to a kind ofly to the harmless opaquing fluid of ozone, comprise non-halogenated hydrocarbon solvent, polymer phase with mutually opaque, wherein opaque ratio with polymer phase is about 2.2 to about 3.8, and preferred about 2.4 to about 3.6 (based on weight).
Other features and advantages of the present invention will and obviously embody from the description of embodiment preferred.
The term here " rewriting characteristic " is meant that opaquing fluid receives the ability of the new mark of printing ink, marker pen and printer.Not bound by theory, the applicant thinks that this characteristic is and film strength and relevant to the cohesiveness of paper.During when opaquing fluid film toughness difference with to the bad adhesion of paper, its overwrite performance is poor especially.When new mark is marked on the film, cause opaquing fluid cracking and peeling usually.Therefore, the opaquing fluid that embodies good " overwrite performance " too many peeling or cracking can not occur writing normally under the pressure.Good overwrite performance is crucial for ink pens and printer, because their applied pressures are higher relatively.For marker pen, it is so unimportant that good overwrite performance generally seems.
According to the present invention, find, by the ratio of adjustment, can obtain obvious improved overwrite performance based on the opaque and polymer phase of the opaquing fluid of non-halohydrocarbon.
The term here " opaque phase " is meant the total amount of opaque reagent in the opaquing fluid.Be applicable to that opaque reagent of the present invention comprises the blend or the mixture of commercially available rutile titanium dioxide, anatase titania, zinc sulphide, zinc oxide, lime carbonate or these materials.The median size of preferred opaque reagent is at about 0.2 to about 0.4 micron, average oil suction degree from about 6.3 kg of oil/45.4 kilograms of colorants to about 16.3 kg of oil/45.4 kilograms of colorants.The amount of opaque reagent can be determined (relatively poor spreadability is provided more on a small quantity, and more amount provides obvious opaque spreadability) according to its required level of coverage.Usually based on about 32wt% of composition total weight extremely the amount of the opaque reagent of about 55wt% be suitable for.Preferred opaque reagent is selected from rutile titanium dioxide and anatase titania, its usage quantity be based on composition total weight about 38 to about 52wt%.
The term " polymer " phase here " be meant film-forming binder (being resin), softening agent and dispersion agent.Be applicable to that binding agent of the present invention comprises thermoplastic methacrylic butyl ester (BMA) multipolymer (Neocryl that produces as the Zeneca Resins of Wilmington, masschusetts, u.s.a
B705 or Neocryl

2044); N-BMA/Propenoic acid, 2-methyl, isobutyl ester multipolymer is (as the Elvacite of chemical company of Du Pont
2046), and composition thereof." softening agent " that is suitable for comprises phthalic acid two-tridecyl ester.The dispersion agent that is suitable for comprises Sodium docusate and the polymkeric substance aliphatic ester (Hypermer that ICI Americas company produces
LP1); And composition thereof.
The term here " non-halogenated hydrocarbon solvent " comprises any hexanaphthene or alkylation hexanaphthene and the aliphatic hydrocrbon and composition thereof that contains 10 or carbon atom still less.Preferable material is a methylcyclohexane.
Opaquing fluid of the present invention not necessarily comprises other typical opaquing fluid component, and toning agent for example is as carbon black, raw unmber, iron oxide yellow etc.These toning agents also count in the opaque reagent of " opaque phase ".The tori seed oil that also adds a spot of (0.1-0.2%) in addition is as stopping agent (deterrent).
According to the present invention, opaque ratio with polymer phase is 2.2 to 3.8 o'clock, compares with traditional non-halogenated hydrocarbon solvent type opaquing fluid system, has excellent rewriting characteristic.Opaque ratio with polymer phase is preferably 2.4 to 3.6.
